• Currency of line to the data control Bean

  Hello

  JDev: 11.1.1.7.1

  We have created a list of POJO Bean data control. This has been used as a table. An iterator has been created on the pagedef on control of bean data.

  What we observe is that the table selection listener is unable to choose, because there is no change of line. Any suggestions on the best practice to keep currency row for control of data iterators based Bean?

• Delete all the rows in a data control Bean

  I use JDeveloper 11.1.1.6
  
  In my case, I have a screen that interacts with a data control Bean I followed the steps in the following URL to create a Bean data control
  
  http://docs.Oracle.com/CD/E18941_01/tutorials/jdtut_11r2_36/jdtut_11r2_36.html
  
  My screen successfully interacts with the data control Bean. This form lives in a stream of delimited tasks (BTF). I can add lines using a link create insert and can delete rows as well. Once the user gets all the lines in the data of beans control they want inserted in a DB table, I can browse the data control Bean and publish those documents to the DB. It is possible for users to add rows to the data control Bean and then link to a new brand screen located in a different BTF that leaves lines in the data control Bean. Now, the user returns to the original screen. On his return, I would like to empty (erase all lines) for bean control data so that they have a new start. Could you please advise on what I need to do to be able to clear a data bean control when you enter a BTF

  You will need to add a method to your bean which clears the Collection that contains your data.
  You can then drag this method to your pageflow as a methodCall and invoke it when you navigate from one page to another.

• With the help of AMPA on non - WS Data Controls

  Hello community MAF .

  I'm developing an Application of MAF that consumes the REST API of WebCenter portal (which is based on the model of HATEOAS).

  I want to make powerful from scratch, including the following:

  -Offline mode (using the SQLite).

  -Persistence, of setting cache and synchronization using AMPA.

  Looks like it's not easier to apply directly on the REST API of WCP AMPA.

  The REST API of WCP is the result of a call of two steps:

  1) authenticate using BASIC authentication against http://Host/repos/api/resourceIndex for the utoken

  (2) use utoken as the URL parameter for the next call of REST for the specific service.

  I know that the Bus Service could be a possibility on the creation of a more simple REST on the WCP REST API, but is not an option right now because that is not easy to map.

  My questions are:

  (1) can we use AMPA on data controls in Java that will call internally to (DB in case of offline mode, REST by program in the case of online mode).

  (2) can define us manually in the persistenceMapping.xml?

  (3) is there anything else more easy to use wizards with HATEOAS base based Services?

  Thanks in advance

  Kind regards.

  Daniel,

  Why is it not service bus an option? You say 'not easy to map', but do the mapping in the MAF makes it not easier, it? the REST API of pressurization is not very easy to mobile, so this transformation to a more usable by using bus service API cost as a good idea for me. See also this article from the A-team.

  Answers to your questions:

  (1) Yes, this is the added value of nucleus of AMPA. You get a service generated the DTC Assistant classes, then you turn this class in a bean data control and use this data control bean for the construction of your user interface. The service class will access local DB and the service REMAINS remote. By default, AMPA will directly show the current data of the local DB, and then in the background call the REST service (online) and refresh the UI, once the REST call has been processed. But this behavior is very configurable and can be changed as you wish.

  (2) Yes, of course, you can manually create data objects, classes of service and persistence mappings, but the wizard is generally much faster.

  (3) HATEOAS logical not for the dynamics of UI where the next action is determined by a link returned in the payload. It is a different model from the static of the UI we build in general with MAF. What is your problem with the help of the wizard of the AMPA?

• oracle.jbo.NoDefException: Houston-25058 POJO data control

  Hello.

  I had a problem where I get the following exception:

  oracle.jbo.NoDefException: Houston-25058: groupLabel of definition of the attribute type is not found in ViewDefgroups3_254.

  Here is the description:

  With the help of:

  12.1.3 JDev (Build JDEVADF_12.1.3.0.0_GENERIC_140521.1008.S).

  JDK 1.7.0_79

  
  

  In my application I have XSD which was used to generate the content model (next classes of java: Project.java (as the main class of the model), GroupsType.java, ThemeType.java).

  Data control was created on this model (POJO data control).

  When I was creating a data control I also create wrapper class (for additional functions) - ProjectWrapper.

  
  

  Created data control has the following structure:

  ProjectWrapper:

  attributes of the project

  groups (collection):

  group attributes of

  themes (collection):

  attributes of theme

  After I did drag GROUPS onto the page and create trees that have the following structure (lets call it groupsTree):

  groups:

  groupLabel

  themes:

  themeLabel

  
  

  In pageDef there are:

  < Tree IterBinding = "groupsIterator" id = "groups" >

  < nodeDefinition DefName = "ru.project.GroupsType" Name = "groups0" > "

  < AttrNames >

  < item Value = "groupLabel" / >

  < / AttrNames >

  < accessors >

  < item Value = "themes" / >

  < / accessors >

  < / nodeDefinition >

  < nodeDefinition DefName = "ru.project.ThemeType" Name = "groups" path1 = TargetIterator"${bindings.themesIterator}" > "

  < AttrNames >

  < item Value = "themeLabel" / >

  < / AttrNames >

  < / nodeDefinition >

  < / tree >

  I also add:

  < action IterBinding = "groupsIterator" id = "ExecuteGroups" InstanceName = "ru.project.ProjectTypeWrapper.groups" "

  DataControl = "ProjectTypeWrapper" RequiresUpdateModel = "true" Action = "iteratorExecute" / >

  After starting my application, load the XML data in the content model and executes the ExecuteGroups action.

  In the application page all items that show the project attributes are filled with data.

  but when he goes to make application groupsTree throws the exception mentioned above.

  Interesting thing here that when I recreate the data control in the class of the project (without using the wrapper class).

  application works very well without any exception.

  Any ideas why this happened?

  Post edited by: Don Kleppinger confirmed it happens on 11.1.1.7 as well (see image)

  Frank Nimphius-Oracle

  I have a work around for this bug to Oracle.  I have a version in 037 sample that actually works and that will sort the field date.  I'm ready to download a copy to replace the download version that is there if Oracle is listening.  The sample was there 5 years ago so it is regrettable that this bug still exists.

  That's what I did

  create beans with custom queryListener

  On the table

  change

  queryListener = "#{bindings.allEmployeesQuery.processQuery} '"

  TO

  queryListener = "#{queryListenerBean.processQuery} '"

  Add an additional field to the line which is a long value of the Date column.   In the queryListener I change the input filter on the value of long type instead of the date value.

  I do not display the column containing the value of long (time) in the table, but she must appear in the binding of the tree. (shuttles to the right)

  In the listener query

  • Read the filter value Date and read the value of time full, clear the value of the filter date
  • long time set in the filter
  • Run the query by call of the listener of the original request #{bindings.allEmployeesQuery.processQuery}
  • Set the date value to the value entered by the user
  • erase the value of long type

  Here is the code

  {} private void processQuery (QueryEvent queryEvent)

  Table richeTableau = (RichTable) queryEvent.getComponent ();

  FilterableQueryDescriptor filterQD = (FilterableQueryDescriptor) table.getFilterModel ();

  Card filterCriteria = filterQD.getFilterCriteria ();

  Date dt = (Date) filterCriteria.get ("hireDate");

  time of to of subject Date and filter on hireDateLong instead of column hireDate column

  containing the value of long type of date instead of the Date

  If (dt! = null) {}

  TM long = dt.getTime ();

  filterCriteria.put ("hireDateLong", tm);

  filterCriteria.put ("hireDate", null); This must be null or will not work

  }

  DCBindingContainer bc = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  Object execBinding = bc.findExecutableBinding ("allEmployeesQuery");

  does not perform a cast of the class internal oracle but another technique guided under

  does not work with POJO data control

  run the filter

  (ExecBinding) .processQuery (queryEvent) (FacesCtrlSearchBinding);

  This will fail

  invokeQueryEventMethodExpression ("#{bindings.allEmployeeesQuery.processQuery}",)

  restore the value of the filter if he continues to display in the QBE bar

  filterCriteria.put ("hireDate", dt);

  filterCriteria.put ("hireDateLong", null);

  }

• Return of the bound data control method causes IllegalArgumentException

  JDeveloper Version: _12.1.2.0.0_GENERIC_130608.2330.6668

  Problem:

  I have a Service method on a data control which takes the parameters. I'm able to drag the Service method on a JSF/ADF page and it creates an ActionBinding and all links in the input parameter as well. No problem. I can run the page and enter values in the display, press the binding Action and the method on the façade of the Session is called perfectly. So far so good. Now, I want to display the results of the (returned as a collection of POJO) Service method in the method declaration.

  If I drag the method declaration of data control on the same page and request that the results will be displayed in a table (or any control that will display a collection, in this example, this is a graph) control is created and all links with her. Once again, so far, so good.

  Now I start the page. This time, I IllegalArgumentExceptions (two of them) returned as messages when loading the page. Stack trace looks like this (my apologies, I hate when people put a huge stack traces in positions):

  Now, if I fill in the parameters on the screen and call the ActionBinding by pressing the button created, the method calls the function on the façade and the data is returned in the control (chart or table). From that moment, I never have the illegalArgumentException and the page the way I want it.

  So, my question is, why the return of the method lie I invoke a method call on a page load until the ActionBinding is called and give me an illegalArgumentException. And - most importantly - how can I avoid this error?

  Any advice would be greatly appreciated.

  
  Thank you

• Impossible to obtain the data controls to display the browser of the application

  I installed JDeveloper version 11.1.2.3.0 on a Workstation Windows 7 (SP1). Once installed, I decided to try the [get started with the JDeveloper IDE | http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_50/jdtut_11r2_50.html]. After you have created "MyFirstApplication" I noticed that I couldn't see the accordion of data controls, as shown in the example. I decided to ignore it and continue with the rest of the tutorial, hoping he could enlighten us. No chance and ran into other problems that surround the stage 13, when I could not create a managed bean as illustrated in the example.
  
  So I went back to the first problem of the accordion of missing data control, suspecting that this may be part of the problem. I searched and found several issues here in the discussion that resembled the may be solutions to the problem and tried them all:
  (1) remove the system11.1.2.3.39.62.76.1 directory and restart JDeveloper = > nothing helped, still missing data controls
  (2) uninstall all versions of Oracle Middleware installed on the PC, removal of the JDeveloper user directories, restart and reinstall only the version 11.1.2.3.0 (there was also an old 11.1.1.4 version installed) == > didn't help, still missing data controls
  (3) made a new software download where jdevstudio11123install.exe has been altered somehow. Repeated step 2 = > nothing helped, still missing data controls
  
  I'm pretty much running out of options now, is there any other mystical step I missed that can work?
  I feel, I'm not the first to experience this problem, but I can't find a solution with the search function of this forum.
  
  Any help is appreciated.

  Try to open up JDeveloper from the terminal and see if there are errors. Also in the screenshot, I don't see that you have all the projects exposing DataControls, so create a java class and right-click on it, create a DataControl and see if this stage support the feature.

• Regarding the Model layer and data controls

  Hello
  
  I have a small query on the design of an application of the ADF.
  
  Scenario:
  I have a class (Model.java) in the model layer queries who manages all databases and the calculation of the other partners.
  I have a class (BackingBean.java) in the view events related to the layer of controller, which is a bean of support and manages all actions.
  
  Query:
  How to access the methods of Model.java of BackingBean.java for that architecture is not broken.
  
  Proposed solution:
  1. I create a data control that exposes all the methods and I give a call back bean by using the binding operation
  2. I call directly the Member of the class of functions of bean support and not through data controls.
  
  Which should be a better approach to 1 or 2 or any other suggestion.
  
  Thank you

• ADF task flows and parameters WITHOUT data controls

  Hello world.
  
  In a previous post, I asked him about the best way to call the workflow "at a distance" by a "local" application Frank Nimphius suggested me to use the JAR ADF libraries between projects for this. I'll apply, but I have a small/big problem:
  
  As I said in my previous post, I exclusively use the EJB 3.0 - JPA technology in all my projects. The components business or data controls are used. Just a lot of Java-based components.
  
  Now, supossed that I have a (based in the HR schema) application with 3 projects:
  
  -L' one with all things EJB: entities from tables, session bean, and an example of a Java client.
  -The second as a 'local' point of view, with a JSPX (viewLocations.jspx) page that contains the table of communities (table_locations).
  -The third view "at a distance", with a JSPX too (viewCountries.jspx) page that contains the table of countries (table_countries).
  
  I have a button in views the remote, and one to switch from local to remote display and the other for the opposite.
  
  The goal is: pass a location of choice of table of locations for the project where I need to see the country for the selected location.
  
  In the table of locations, I use a variable currentLocation (declared as: private location currentLocation = new Locations() ;) to store the selected location and a SelectionListener process, called selectLocation_listener() with this code in the)
  backing.viewLocations.ViewLocations.java:
  
  + ' public void selectLocation_listener (SelectionEvent selectionEvent) {+
  + / / Add code from the event here... +.
  currentLocation = (rentals) table_locations.getSelectedRowData ();
  +}+
  
  If the selected location is stored in the variable currentLocation.
  
  Both in projects the and remote, in that I store the task flow JSPX pages. I have the taskLocal.xml as an unlimited workflow with the viewLocations.jspx as the main view and the taskRemote.xml as a workflow bounded with the viewCountries.jspx as the main view.
  
  I have deployed the project remotely in a library JAR ADF and imported to the local project, then I get it as a special activity Flow call.
  
  The question is: How can I pass the variable currentLocation as a workflow setting to my project remotely? I don't have any data control to bind to a workflow parameter.
  Should I really have some control of data to store my currentLocation variable and bind it to a parameter? Or there is another way without data controls?
  
  Another fact: local and remote project have a dependency with the EJB project.
  What about dependencies? Have a role in call task workflow activities?
  
  Thanks in advance.
  
  If you would like more information or a more detailed explanation please ask me.

  Hello

  a data control is needed for this. If you only want to use ADF task Flow and manage the component UI lie yourself, then you are good to go with this approach. To add parameters to a call from bounded task flows, have a look here

  http://download.Oracle.com/docs/CD/E15523_01/Web.1111/b31974/TOC.htm (Chapter 15, activities of view URL using 15.3)

  You can make the local variable that is accessible from an accessor method Set/getter bean managed so that you can use EL when you set the value of the parameter.

  Your REST is back JSON or XML.

  The REST data control now supports only the XML responses.

  Here's a demo of use basis:

  https://blogs.Oracle.com/Shay/entry/accessing_remote_databases_from_oracle

  If you return JSON, at this point, you create a Java class that parses the JSON and then to expose this class as a data control.

• Data control does not display THAT POJO returned by the method

  Hello

  I am running JDev 11.1.1.7. In my AppModule.impl, I created a method that returns a simple POJO (which implements serializable) that has two fields of type string. I exposed the method in the client interface of appmodule. In the control of data, the method appears with an element of return instead of an object or any way to access the two fields of type string. I want to display two fields of type string in the output text components on my jspx page. I'm not find documentation on how to do it. Can someone point me to the documentation or tell me how to make this change to the method of control of the return data?

  Thanks in advance,

  Steve

  AM method can return the custom type, but as much as I know there is no support for introspection of object at design time.

  (so you can call it programmatically and cast to the appropriate type, but you can do component DND data control).

  So, option 1 is to bind the value property of your outputText managed bean fields, programmatically calling AM, fill these properties manually and update your user interface components (note that managed bean must be saved in viewScope or more in order to preserve the values)

  Option 2 is to create the Bean DataControl (with this you will have DND support)

• Pagination not working not not for POJO data control

  I'm running 37 sample downloaded from here.  The PDF indicates to post in this forum for issues found examples so here I am.

  037. how to build the pagination in the POJO ADF data control

  http://www.Oracle.com/technetwork/developer-tools/ADF/learnmore/index-101235.html

  He's talking about Add method to handle paging that takes the index and the beach

  	method called by the link layer of ADF to run paging
  	public list < employees > Edgeham (int index, int range) {}

  However when I run the sample and set a breakpoint on this method, this method never is called. Only the method that retrieves the entire list is called.  Table extracted data ranges that I scroll to the bottom and I see data recovery... popup, but because this method is not called is not really paging to the model only at the link layer, so I don't have any focal point for range all the way to the service call to a web service to support paging.

  No idea how to operate paging?

  Never mind.  I found the problem.  I didn't know that the example had not been fully implemented.  The instructions say to add a DataControlHandler to the DataControls.dcx and which had not been done.  It works after I added that.

• Select multiple choice based on the data control does not not value in the correct form

  Hello, I am using JDeveloper 12.1.2

  I made a choice of several select based on an attribute of the year to a data control and I have a method in my managed bean that retrieves the selected values in the select choice of many, and on the basis that I want to do some queries, but the value that returns the selection is not the value of the attribute is the value of memory (or what is the correct value name..)

  Here is the code:

  < af:selectManyChoice value = "#{bindings." Label AnoList1.inputValue}' = 'Ano '.

  ID = "smc1.

  valueChangeListener = "#{OBIEE_managed_bean.» AnoListSelection}.

  autoSubmit = 'true '.

  Binding = "#{OBIEE_managed_bean.anoListBinding} '"

  immediate = "true" >

  < f: selectItems value = "#{bindings." AnoList1.items}"id ="si1"/ >

  < f: validator binding = "#{bindings." AnoList1.validator} "/ >"

  < / af:selectManyChoice >

  Managed bean:

  public void AnoListSelection (ValueChangeEvent valueChangeEvent) {}

  valueChangeEvent.getComponent () .processUpdates (FacesContext.getCurrentInstance ());

  try {}

  System.out.println ("Valor link yearChoice:" + anoListBinding.getValue () m:System.NET.SocketAddress.ToString ());

  ...

  The output is as follows:

  Valor link yearChoice: [Ljava.lang.Object;@4939cade

  Year: Ljava.lang.Object;@7135da60

  This normally happens when the toString is not defined, but how I have to fix this? Someone at - it had the same problem? Any advice?

  Kind regards

  Frederico.

  Hi Frederico

  I'm fine hope you are too.

  Sorry, but you can try

  {for (Object item: (Object []) {valueChangeEvent.getNewValue ())}

  System.out.println (Item.ToString ());

  }

  This should give you something.

• View the data in different data control

  JDev 11.1.1.5.0 BPM

  I have a table from a data bean and control when clicking on a row of this table, I want to display data from another control on different data (Payload BPM) under the table in a form.

  How can I do this?

  Hello

  The payload BPM is exposed by a method I guess. This method takes an argument of the query (?). If this argument is for example an ID of the selected line then...

  1 create a valueAttribute binding by selecting the pageDef file. In the editor, choose the links, then generic link, AttributeValue. Select the iterator used by the table, and then the name of the attribute holding the ID to pass to the BPM method

  2. drag the result of BPM method to the page (and make it as a shape)

  3. the argument of the BPM method card for #{bindings.. inputValue}

  4. set the Partialtrigger property to the ID of the table panelFormLayout

  This should synchronize the form with the value selected in the table
