• display accessor query runs for a long time with parameters null - JDEV 11.1.2.3

  I use Jdev 11.1.2.3.

  
  I have inputVO with the query as

  Select "store", as a double.

  The VO store attribute, I have inputlistofvalues that comes from storesLOVVO, which the query is like

  Select store_name, store_id from all_stores.

  Now I drag store to inputVO on the page of the user interface as inputListofValue. The user selects the value and runs the page and everything goes as you wish and in no time at all.

  Now the user manually removes the selected value from the store of the user interface and clicks a button to deal with something. But instead of calling the method that is present on the actionlistener for this method, the query of storesLOVVO runs on the server (I can see in the newspapers) for a very long time with store_name as null as a condition.

  If I run this query in SQL developer, it gives results in 0.02 sec, even with store_name as null clause added.

  Why jdev performs this LOV VO when there is no parameters?

  And if she runs the VO, why are so slow... its almost take 2 minutes and then the rest of the processing occurs.

  Yet,.

• Component attribute declarative for action in the link layer

  Hello
  
  I have a component declarative which includes buttons to add/remove/save/cancel that I hope to use to the standardization of page layouts. I need to assign two properties for each button, the actionlistener and the enabled property.
  
  For the button of validation for example I would attribute actionlistener for * #{bindings.Commit.execute} * and I would set the enabled property to * #{! bindings.Commit.enabled} * which would allow the validation button only if there was something to engage, if the action of CreateInsert had been carried out for example.
  
  And I would create attributes in the declarative element to these two parameters.
  
  What I want to know is is there a way that I can pass the action itself #{bindings.Commit} as an attribute in the component declaration so that I can reduce the number of attributes (and ease of development), and if yes, what type this attribute will be.
  
  Thank you

  Hello

  Create an attribute of type OperationBinding (full path) and you're good to go. I did the same thing with the DCIteratorBinding

• How to call javascript method action listener.

  Hi Experts ADF,

  JDEV version 11.1.1.7.0

  I cb2 and cb1 button, 2. I call the pressing cb1, cb1 - actionListener () method. I invoke the javascript cb1() method.

  And JavaScript, I need to invoke the command button 2 actionListener. How do I get there?

  I tried the below code but its not invoking is not the cb2_actionListener.

  
  var button
  = AdfPage.PAGE.findComponentByAbsoluteId ("cb2");
  ActionEvent.queue (button, true);

  Thanks in advance,

  Animesh

  HI Anne

  If you have created actionListener for button cb1 cb2 actionListener call you in this

  See - Blog of Ashish Awasthi (Jdev/ADF): call to Action button by programming, Queuing ActionEvent

  Or if you insist on using Javascript then try this

  var component = AdfPage.PAGE.findComponentByAbsoluteId (commanButtonId);

  AdfActionEvent.queue (component, component.getPartialSubmit ());

  
  

  Thank you

• the operations are missing in the binding

  When I got to the actionListener for my setup command button, I don't see operations (clear, validation, etc.) in the binding. What could be the reason?

  Drag you & drop operations of validation/deletion of the data control palette? If you do, the operations will be created in pagedef.
  otherwise, you would need to create manually on the FED page.

• SetActionListener in Access table column of the row

  I use JDev 11.1.1.6.
  
  
  I use a group header form. In the form, I have a menu and a read-only table.
  
  The measure has multiple columns and multiple rows of data. The menu has a command link in which I need to pass parameters through the scope of the request to the stubborn workflow I call. In the command link I am trying settings requestScope with a setActionListener. The settings are currently hardcoded and validated in the corresponding requestScope settings. Based on the parameters that I'm passing hardcoded called and page rendering workflow are correctly.
  
  I would like to switch dynamically from the properties of one of the columns for a given row selected in the table. Because the menu with the command link is not included into the table, I can not access the variable 'row' of the table.
  
  The question I have is how can I access a column value for a given line in the table when you use the setActionListener in my menu. I also read that I might want to use setPropertyListener instead, but I think I have the same problem to access the data in the row.

  You have to use actionListener for this.

  
  Text = "..." »
  actionListener = "#{.onMenuClick}" "
  action ="" / > ".

  {} public void onMenuClick (ActionEvent actionEvent)
  Add the code in the event here...
  Learning purposes - view select a clicked button
  System.out.println ("navigate to the clicked link page');
  Get the links associated with the current scope, and then access that we assigned to our table - for example OpenSupportItemsIterator
  DCBindingContainer links =
  (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();
  DCIteratorBinding = dcItteratorBindings
  bindings.findIteratorBinding ("OpenSupportItemsIterator");
  Gets an object that represents the table and which can be chosen that it contains
  ViewObject voTableData = dcItteratorBindings.getViewObject ();
  Get the selected line
  Line rowSelected = voTableData.getCurrentRow ();
  print
  System.out.println ("Number of DC" + rowSelected.getAttribute ("DcNum"));
  ADFUtil.setEL ("#{requestScope.DcNumber}", rowSelected.getAttribute ("DcNum"));

• Save button.

  Hi experts jdev,.

  I know that mandatory flag in OT. It's ok.
  
  
  I do not want mandaory Pavilion.
  
  instead.
  
  for example:
  
  EMP no: //here user doent entered in this field
  
  Name of EMP: //here user is not entered in this field too
  
  Save button
  
  
  If the user click Save middle button. EMP no and Emp is not registered. Please enter the required details unless you can perform a save operation.
  
  and do not commit anything in the dbtable. take this error until the user entered for the value.
  
  How do this programtically. ?

  Hello

  Use of the extract below to validate and report errors programmatically.

  And configure the validateMandatoryFields method in the ActionListener for your button Save.

  public String validateMandatoryFields() {
  FacesContext fc = FacesContext.getCurrentInstance();
  String empNoEntered = (String) getEmpNo().getValue();
  String empNameEntered = (String) getEmpName().getValue();
          if(empNoEntered == null) {
              UIComponent uIComponent;
              uIComponent = empNo; // Typo mistake here... empNo holds the reference to the Input Text field Component.
              FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR,
                "Emp Number is not entered",
                "please entered the mandatory details unless you can perform save operation");
              fc.addMessage(uIComponent.getClientId(fc), message);   // Associates the Message with the Emp No UI Component
              ((RichInputText)uIComponent).setValid(false);  // On click of the Save button programmatically making the Valid state to false

• AF:treeTable want to expand all of the nodes.

  Hello
  I use jdeveloper Studio Edition Version 11.1.1.3.0
  
  I have af:treeTable. I want to expand all nodes after clicking on af: commandButton. How can I do this?
  
  < af:treeTable value = "#{bindings.department2.treeModel}" var = 'node' "
  selectionListener = "#{bindings.department2.treeModel.makeCurrent} '"
  rowSelection = "single" id = "tt1" initiallyExpanded = "true" > < f: facet name = "nodeStamp" >
  < af:column id = "c2" >
  < af:outputText value = "#{node}" id = "ot2" / >
  < / af:column >
  < / f: facet >
  < f: facet name = "pathStamp" >
  < af:outputText value = "#{node}" id = "ot3" / >
  < / f: facet >
  < / af:treeTable >
  
  If I used initiallyExpanded = true. It expand only the first node.i want to expand any swelling after clicking on the button.

  For all nodes in a treetable can be expanded, you will need to add all the rows of the disclosedRowKeySet.

  (1) create a binding for the treetable in average managed code as "treeTable.
  (2) in the actionListener for the commandButton control, call the following method 'expandTreeTable ':

  {} public void onExpandButtonClick (ActionEvent actionEvent)
  this.expandTreeTable ();
  }

  private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();

  private void expandTreeTable() {}
  If (this.treeTable! = null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  Model CollectionModel = (CollectionModel) treeTable.getValue ();
  JUCtrlHierBinding = treeBinding
  (JUCtrlHierBinding) model.getWrappedData ();
  JUCtrlHierNodeBinding RootNode = treeBinding.getRootNodeBinding ();
  disclosedTreeRowKeySet = treeTable.getDisclosedRowKeys ();
  If (disclosedTreeRowKeySet == null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  }
  List = firstLevelChildren
  rootNode.getChildren ();
  for (node JUCtrlHierNodeBinding: firstLevelChildren) {}
  List ArrayList = new ArrayList();
  List.Add (node.getRowKey ());
  disclosedTreeRowKeySet.add (list);
  expandTreeChildrenNode (node, treeTable, list);

• Jdev 11 g - change visible attribute of another object based on click

  Hi there all,
  
  I'm new to Jdeveloper, ADF and am initially impressed by the amount of information and tutorials on the web. I was able to successfully create my own search and display type applications using the PPR and a few other nice features.
  
  However, I am looking for a technique that will allow me to hide or display another object based on a click.
  
  I saw a few guides that guide you through the creation of Java code, but descriptive, it seems that I should be able to put a condition on the visible tab.
  
  If Yes, can someone help me with this syntax? If this isn't the case, I need to create a ManagedBean? Or a PageFlow? These are all terms, I'm new too, please bear with me. I would have thought, that I could choose an event "click" or something like that and the target property. I think with JDeveloper, I would need to bind the object to a listener of some sort.
  
  Help much appreciated!
  
  
  Simon

  As you will be required to show/hide other components based on the click of a button, would need you the component references in the managed bean and to ensure that changing the visible property is reflected on the component, you would use PPR.

  To illustrate the use case that you mentioned, we have two buttons namely show & hide to show/hide an inputtext component.

  (1) create a page named SamplePage.jspx
  (2) create the necessary components on the page.
  (3) create a managed bean class named SamplePageBean & save the bean in the adfc-config file in requestScope.
  (4) create a reference for the inputText component in the bean managed as inputText.
  (5) on the actionListener for each of the buttons property, create a method to show/hide the inputText component by setting the respective property.

  The Code snippets include:

  (1) SamplePage.jspx

  
  
  xmlns:f = "http://java.sun.com/jsf/core".
  xmlns:h = "http://java.sun.com/jsf/html".
  xmlns:af = "http://xmlns.oracle.com/adf/faces/rich" >
  
  
  
  
  
  actionListener = "#{SamplePageBean.onShowClick}" / >
  
  actionListener = "#{SamplePageBean.onHideClick}" / >
  
  Binding = "#{SamplePageBean.inputText} '"
  partialTriggers = 'cb1, cb2' / >
  
  
  
  

  (2) SamplePageBean.java

  package view.bean;

  Import javax.faces.event.ActionEvent;

  Import oracle.adf.view.rich.component.rich.input.RichInputText;

  public class SamplePageBean {}
  private RichInputText inputText;

  public SamplePageBean() {}
  }

  {} public void setInputText (RichInputText inputText)
  this.inputText = inputText;
  }

  public RichInputText getInputText() {}
  return inputText;
  }

  {} public void onShowClick (ActionEvent actionEvent)
  this.inputText.setVisible (true);
  }

  {} public void onHideClick (ActionEvent actionEvent)
  this.inputText.setVisible (false);
  }
  }

• Is why my persist() method JavaServiceFacade receives the NULL object

  My version of jDeveloper is 11.1.1.3.0
  
  I have a jspx in which I want to enroll an employee in my DB click on the "submit" button.
  
  I did an entity object (Employee.java) made from an EMPLOYEE table. Then, I exposed this entity using a JavaServiceFacade bean. The JavaServiceFacade class has a method with the signature persistEmployee (Employee employee).
  
  In my UI, I did made a Submit button by dragging the method persistEmployee() of my palette of DataControls on my jspx, and linking actionListener for it is = "#{bindings.persistEmployees.execute}".
  
  Now when I click on the button send, the persistEmployee() method throws an exception that is below...
  _ java.lang.IllegalArgumentException: object: null is not a known entity type___
  
  I found that the persistEmployee() method receives an object used as an argument that makes this error is thrown.
  
  Can someone guide me pls on what could be the problem.
  
  BELOW THE CODE OF VISITS I'VE USED.
  
  .. key code in my jsp...
  < af:commandButton text = "Submit".
  Binding = "#{backing_LdapUserCreation.CB5} '"
  ID = "cb5".
  actionListener = "#{bindings.persistEmployees.execute} '"
  Disabled = "#{!}" Bindings.persistEmployees.Enabled}"/ >
  
  
  .. .method code, which resulted in the javaservicefacade... (here the employee argument received by the first row is NULL)...
  public employees persistEmployees (employees) {}
  System.out.println ("IS used NULL? = "+ employees);
  return (Employees) (employees) _persistEntity;
  }
  
  .. .binding code in my pagedefinition...
  < methodAction id = "persistEmployees" RequiresUpdateModel = "true".
  Action = 'invokeMethod' MethodName = "persistEmployees."
  IsViewObjectMethod = 'false' DataControl = "EmployeeService".
  InstanceName = "EmployeeService.dataProvider"
  ReturnName = "EmployeeService.methodResults.persistEmployees_EmployeeService_dataProvider_persistEmployees_result" > "
  < NamedData NDName = "employees" NDType = "model.test.Employees" / > "
  < / methodAction >

  Hello

  When you dragged the persist from the DataControls Panel method, a dialog box opens that in its lower part shows the argument that the method expects. This argument should be pointed | currentRow | data provider. To do this, click in the value field in the method argument, and then click the button on the right to display the editor of EL. Then, expand the iterator node under the node links. Expand currentRow, then select dataProvider.

  You can do after having created the tying method as well. Select the PageDef file in the Application browser and open the window of the Structure. Expand the persist method: there must be a child element. Select the child element and in the property inspector, set its NDValue property

• ADF 11 g Table entry createinsert - operation I can handle?

  Hello
  
  I am a newbie to the ADF, and trying to figure out how better to this, any help appreciated.
  
  I use JDeveloper 11.1.1.3.0 with ADF BC.
  
  I want to create/remove a table from the user interface. I followed 23.3 creating an editable Table and 23.4 creating a Table of Fusion Dev Guide entry.
  
  Basically, I:
  -Created an entity object, call xxEO
  -Created a display based on the entity object, object call xxEOVO
  -XxEOVO dropped from the range of control of data as a table and adding createinsert ADF, remove, validate the operations to the toolbar.
  
  It works very well.
  
  But now I'm trying to pre-populate a field on each new line was created when the createinsert is clicked. Basically, I don't want the user to be able to change this value, I just want to show a value read-only of the new line, when they hit the createinsert button.
  
  Is there an easy way to do this? What are my options? I don't see any generated code where I can plug my value...
  
  Thank you!
  Kassouri

  You can add the actionListener for the create action in the table as follows:

  public void addRow (ActionEvent ae)
  {
  Links DCBindingContainer = (DCBindingContainer) getBindings ();
  DCIteratorBinding iter = bindings.findIteratorBinding("MyTableIterator");

  ViewObject vo = iter.getViewObject ();

  Line = vo.createRow ();
  row.setAttribute ("MyField1", "value");
  row.setAttribute ("MyField2", "Value2");

  vo.insertRow (row);
  }

  As you don't have pre-filled lines to be changed, please make these columns/attributes read-only.

  Thank you

• CreateInsert: table auto refresh, bug or feature?

  I noticed something strange.
  I have a table that is linked to a domain controller. I also have a button with custom code. In this code, I run the CreateInsert and open a popup.
  It works very well.
  
  I noticed that a blank line gets my table as soon as I press the createInsert button, however there are no partialTrigger from my table to the button. Is this a normal behavior or a bug?
  
  This is the code of my table:
  

  <af:table value="#{bindings.User.collectionModel}" var="row"
                rows="#{bindings.User.rangeSize}"
                emptyText="#{bindings.User.viewable ? 'No data to display.' : 'Access Denied.'}"
                fetchSize="#{bindings.User.rangeSize}" rowBandingInterval="0"
                filterModel="#{bindings.UserQuery.queryDescriptor}"
                queryListener="#{bindings.UserQuery.processQuery}"
                filterVisible="true" varStatus="vs"
                selectedRowKeys="#{bindings.User.collectionModel.selectedRow}"
                selectionListener="#{bindings.User.collectionModel.makeCurrent}"
                rowSelection="single" id="t1" width="850px"
                autoHeightRows="10" contentDelivery="immediate">

  It's the actionListener for my button:
  

      public void createUser(ActionEvent e) {
        BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
        OperationBinding createInsert = (OperationBinding) bindings.get("CreateInsert");
        createInsert.execute();
        
        FacesContext facesContext = FacesContext.getCurrentInstance();
        ExtendedRenderKitService service = Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);
        service.addScript(facesContext,"AdfPage.PAGE.findComponent('"+popup.getClientId(facesContext) + "').show();");
      }

  My button has the partialSubmit = "true" so I don't see why the table is notified and adds the empty line.
  I want to just open the popup and show the field in the record.

  Hi Yannick,

  Seems you and debugger do the same popup and Create/Insert button

  Edit: Ah, I just noticed that you say that you see the line in the table immediately... not sure that one (I see the line after rejecting the popup). I am downloading of clusters of JDev extensions right now, so I can't test my approach immediately, but I'll do it soon.

  Note: I recommend that you use the API server to display the popup rather than injecting JavaScript - see my sample code to this other thread - this method to display a popup is the way documented to do so in an actionlistener.

• Invoking the CreateInsert of a managed bean

  Hi all
  
  I'm trying to call a CreateInsert operation on a view of a method object in a managed bean. The method is assigned as the actionListener for a toolbar button. For this, I modified the file xxxPageDef.xml with the wizard, who introduced something like this:
  
  & lt; action = "CommercialReferenceVO1Iterator" id = "CreateInsertPepe" IterBinding
  InstanceName = "DesignRequestAMDataControl.CommercialReferenceVO1"
  DataControl = "DesignRequestAMDataControl" RequiresUpdateModel = "true".
  Action = "createInsertRow" / & gt;
  & lt; / code & gt;
  
  I invoke the method using the EL from Steve Muench class as follows:
  
  EL.invokeMethod ("#bindings. CreateInsertPepe.execute', null (class), null);
  
  I do something appropriate? Because the truth is, it does not work :)
  
  What I really need, is create and insert a new row into an object of the detail view, and then change the tab currently selected programmatically to display the edit page for the new line.
  
  I hope that my question is at least some logic...
  
  Thank you!
  
  Juan Manuel

  Try this code in your method of action/actionListener managed bean:

  OperationBinding createInsertOp = (OperationBinding)getBindings().get("CreateInsertPepe");
  createInsertOp.execute();
  

  The code only inserts the line. Programatically displaying the edit page for the new line it is something else. If my suggestion is to execute the code inserts really the only line. If its ok, then just add the code that automatiaclly displays the edit page. In this way we can isolate the problem.

  Make sure the CommercialReferenceVO1Iterator is in the iterator header for the CreateInsert to work on a ViewObject detail.

  Another thing is that in your pagedef, I noticed the action links, the 'Action' attribute has the value "createInsertRow". You use charger 11 g? I don't know if its new in 11g but I use ADF 10 g and the attributes of 'Action' have numeric values, where a CreateInsert operation would have an Action = "40".

  Best regards
