• To access a page method call parameters jsf page fields

  I have a workflow with a single method, call the execution after a point of view (jsf page).
  
  The view is a jsf page that allows to edit several fields to then filter a view object. This inputtext fields - components in general-have no connection.
  
  The next step in the workflow is executing a method call that takes these parameters - values entered previously in the jsf page - and to run a vo.setwhere and then a vo.exeuteQuery methods but I need the input provided in the previous page. I don't know what is the best method to get access in the ADF.
  
  I usually pass parameters to the method call in the page 'Change the binding of the Action', section 'settings' via EL expressions.

  You can have a support with scope pageFlow bean and bind the attribute to the property value as John mentioned. However, if you do not want to generate a bean, you can simple binding to a pageflow scope variable (might be created automatically).

  Something like

  value="#{pageFlowScope.someVariable}"
  

  and then for the methodCall activity, set the value of the parameter to the same as above EL.

• JDev 11.1.2.1 method Execute (with bind variable) before the page is displayed

  Hi all
  
  I have a view object with a query that uses a variable binding. I drag the data on my .jsf page control to create a table. I create a query method on a bean in sight. The query method uses the content of one of the attributes of the bean to set the link for the query variable:
  
  vo.setNamedWhereClauseParam ("CraIdBindVar", sessionBean.getCraId ());
  
  I put a button on the page that calls the method of the request and it fills the table. That's fine, but I don't want the user to have to click the "query" button when browsing this page. I found forums dealing with create an AMImpl.jave method, create a link on the page, create an executable file for the link. It works that the method is executed until the page appears. However, the AMImpl method cannot call sessionBean.getCraid () to obtain the data required to complete the binding variable.
  
  Is it possible to run my method of view range bean before the page is displayed? Or maybe a way for the AMImpl.java method to access the range of view variable?
  
  Thank you, Steve

  Steve,
  You can drag a call method on the workflow activity. Select the new method call activity, and open the property inspector. Here you choose your bean method in the method property. Now, first of all, you go to this activity of method call, then the page.

• Call the method call activities before you navigate to the target jsf page

  Dear all,

  I use JDeveloper Studio Edition Version 12.1.3.0.0.

  Requirement:

  I have a stubborn taskflow. The stubborn workflow is without using page fragments.

  I have three pages: login.jsf, admin.jsf, user.jsf. I have a method call activity in the taskflow. The login.jsf is the default page. The page of login.jsf have an af:selectOneRadio with two af:selectItem: Admin and user. It also has an af:button. When the user select the af: af selectItem: selectOneRadio and click on the af: button, it should call the method call activity (doLogin) and based on logic it will redirect to the page admin.jsf or user.jsf page.

  Please find the taskflow below:

• call before jsf fragment bean method

  Hello
  
  I have a task flow that call first.jsff (jsf fragment), in first.jsff there is a next button, clicking on which he goes to the other jsff.
  
  1. for first.jsff, I created a bean called FirstBean.java in pageFlowScope
  2. for second.jsff, I created an another bean SecondBean.java in pageFlowScope.
  
  Using the task flow intializer I can put my custom intializeFirst() method to be called before first.jsff gets made, but I need to call some method secondIntialize() before second.jsff (second.jsff is rendered when we click the button following first.jsff)
  
  one way to do initialization in the constructor of secondBean.java but I need I have my custom method call which is the best possible way?

  You can use a method call activity in your workflow.

• How to pass attribute values after ExecuteWithParam to the method call

  Hello
  
  I use Jdev 11.1.1.6.
  
  My use case, is that I have mainPage BTF which has ExecuteWithParam as the default activity. It filters the VO using params. I have a requirement to store some of the attributes of current line to pageFlowScope which must be sent to several taskflows child.
  I present a method call after the ExecuteWithParam event and before the page is rendered but do not know how should I pass the current line (or something) in this method call to store values on pageFlowScope.
  
  What should I switch to this bean managed to store values on pageFlowScope? Is there an alternative?
  
  Thank you
  JAI

  I see two possible ways to get to the attributes. First of all, you can get the iterator current rank and get attributes here. Secondly, add you links attribute in the file pageDef methods for all attributes that you are interested in. Then you access it by using the attribute binding. I never tested the 2nd method, but I guess that the framework will fill the attribute links, as it does in a normal page.

  Sorry, can't give you enjoy this code adds that I'm not in front of a PC.

• Method of child Taskflow in running the taskflow parent page

  Hi all
  
  I have a problem with the verification of data incorrect form Parent Taskflow button to check the incorrect data update in the display of the child page Taskflow object.
  
  JDev version: 11.1.1.3
  Scenario:
  External container page a back button to check child Casil taskflow gave incorrect update or not. Child Taskflow transaction is always create new transaction and not shared. But ControllerContext, root: service always related to the other viewobjects that is loaded in other tabs of the external container page, which is also incorrect data verification of an another tabs viewobject given incorrect archive (I must avoid this problem that's why does not not for me with the context of the controller). I'm thining to execute the method of taskflow of child in the parent on the back button to check the incorrect data update for the page the only tabs only. To do this, how can we child access taskflow method of parent with taskflow static region page. Is there a solution to implement it? Thank you very much.
  
  -Robin

  Hello

  This should work:

  1. child tasks flow setting entry has "parentBean" defined.
  2. the child workflow has a managed bean 'ChildBean' defined in pageFlowScope with a "parentBean" with the property setter/getter.
  3. the parentBean entry of parameter references (in its value property) #{pageFlowScope.childBean.parentBean}
  4. the parent bean is configured on the workflow view parent (viewScope) and passed as a parameter of task flow binding entry. The parent bean has a Boolean property "childFlowTransactionDirty".

  This allows the bean to the child to call the parent bean childFlowTransactionDirty to tell him that the transaction is dirty. On the parent view, you would simply check the status of parentBean for this property.

  Is then how do you set the value to the parentBean of the childTaskFlow. One option is to use a RegionController on the file views PageDef ADF bound in the child workflow.

  public class MyRegionController implements RegionController {
  
      public MyRegionController(){
      }
  
      public boolean refreshRegion(RegionContext regionContext) {
       int refreshFlag = regionContext.getRefreshFlag();
  
        //get access to the ChildBean and its parentBean property. Then call
        //ControllerContext .... to check the transaction state
        //update the childFlowTransactionDirty property
  
        ((DCBindingContainer)regionContext.getRegionBinding()).refresh(refreshFlag);
        return true;
      }
  
      @Override
      public boolean validateRegion(RegionContext regionContext) {
          regionContext.getRegionBinding().validate();
          return false;
      }
  
      public boolean isRegionViewable(RegionContext regionContext) {
          return regionContext.getRegionBinding().isViewable();
      }
  
      @Override
      public String getName() {
          return this.getClass().toString();
      }
  }
  

  Next: When users on the back in the parent view button, you call the ParentView bean childFlowTransactionDirty to check the child task debit transaction to be dirty or not

  Hello

  It contains only the activity of the method, and if so, why is he launched with the help of a new transaction? Note that navigation always is an ID of the view and the workflow will not run if there is no view to navigate to. So either the calling flow calls this workflow and workflow returns immediately after execution of the activity of default method then it refers to a display of flow tasks calling or you add a view. Note that cookies are set on the response of a call and it is not issued before coming to a view. For this reason, using a method call activity could be a bad approach to try this so a phase listener is better suited

• The ADF workflow initializer is called before after the settings?

  My workflow has several parameters, some of which are optional.
  It is not clear in what order are called methods set for parameters, nor is it appears from the documentation that the initializer for a workflow is called before or after the set methods for parameters of the workflow are called.
  I want to call a method, once all parameters have been set. I can do this with the initializer?

  They must be defined at the same time that the initializer is called. Oracle guarantees not the order in which they are defined and customer should not count on that. If you are interested in looking under the hood some more watch this blog post:'t-fit-all.blogspot.com.au/2010/10/jdev-programmatically-capturing-task.html http://one-size-doesn

  If your end goal is to call a method once the parameters are defined, simply include a call to the method as a default activity in your workflow. It is usually my preference when I don't want to make the programmer next abreast of all treatments applicable to the main object of the workflow. The previous link is the exception, as it was written for purposes of logging, and my preference is not to clutter the workflow with logging code.

• called before loading info

  Hey there all you Flash AS3 masters, got a question I am hopeing you can all help me solve.

  In my document class, I have the following.

  var mainBoards:LoadXMLData = new LoadXMLData ("Main_boards.xml");

  var test: XML = mainBoards.getXMLData;

  In the LoadXMLData class, I have an event listener and a Get accessor that returns XML data.

  _urlLoader.addEventListener (Event.COMPLETE, onDataLoaded);

  _urlLoader.load (new URLRequest (file));

  and

  public function get getXMLData (): XML

            {

  return _xmlData;

            }

  It seems that the get accessor (var test: XML = mainBoards.getXMLData ;) in the document class are called before the COMPLETE event in the LoadXMLData class is finished and method of onDataLoaded, thus showing the test property in the document as a null class when I draw...)

  I tried a while loop, but it seems to just crash flash.

  var mainBoards:LoadXMLData = new LoadXMLData ("Main_boards.xml");

  while(mainBoards.getXMLData == null)

                 {

  trace ("data xml not loaded");

                 }

  var test: XML = mainBoards.getXMLData;

  trace ("test proparty" + test);

  is there a better way to wait until data from the XML file are loaded into the LoadXMLData object before the mainBoards.getXMLData is assigned to the test variable in my document class?

  Thank you.

  use:

  in your onDataLoaded() function, add:

  dispatchEvent (new Event ("xmldataLoaded"));

  var mainBoards:LoadXMLData = new LoadXMLData ("Main_boards.xml");

  mainBoards.addEventListener ("xmldataLoaded", getF);

  function getF(e:Event):void {}
  ensure that mothers are not local to a function

  var test: XML = mainBoards.getXMLData;

  trace ("test proparty" + test);

• Message info JSF in the activities of method call

  Hello
  I have a taskflow bounded with an activity of method call that contains a call to a method on backing bean. I would like to put a message of information prior to the loading of the page.
  However, I get NPES from the call to JSFUtils.addFacesInformationMessage (errorMsg) due to the fact that there is no id of root view component.
  Anyone know a solution for this use case?

  Hello

  write in an attribute of memory and have the page check this attribute and display its value. You can use a PhaseListener on the page to add the message memory for faces message stack

• How to execute a method after the user login

  Hello
  I have an application with a public and non-public part. When a connection from the user to the application, I want to execute a method in a session bean to load default data in certain properties in the session bean. How can I execute a method after a connection/disconnection from the user of the application using the ADF security? Is the only Posibility to write a custom plug-in? If so,... How can I easily extend an existing connection module?
  
  Kind regards
  André

  Hello

  How is that you are relying on the login? You can connect to WLS FRO m backing bean (see this ) and if everything is ok, call your session bean method.
  You just need the reference of session bean in your backing bean (@EJB injection (yet?) does not work for the safeguarding of the beans, so either do the JNDI research or expose the method in the pageDef and then solve / execute it in the bean to support).

  Another possibility would be to place - the method call activity after your login to the adfc - config.xml, but this page depends on how you set up logging. So, the first solution should work.
