Contextual event on table not triggered

Question

Using Jdev PS4.
Concider following example: http://www.yonaweb.be/ContextualEvent.zip
(I know following example can be simplified by using master-detail relation in the data control but it's to illustrate the example)
I have two taskflows: EmployeeTF and departmentTf.
The idea is to trigger an event when I select a new record in the department table.
This is the tree binding:
<tree IterBinding="DepartmentsIterator" id="Departments">
      <nodeDefinition DefName="model.views.DepartmentsView" Name="Departments0">
        <AttrNames>
          <Item Value="DepartmentId"/>
          <Item Value="DepartmentName"/>
          <Item Value="ManagerId"/>
          <Item Value="LocationId"/>
        </AttrNames>
        <events xmlns="http://xmlns.oracle.com/adfm/contextualEvent">
          <event name="changeTheDept"
                 customPayLoad="${bindings.DepartmentId.inputValue}"
                 eventType="Currency Change Event"/>
        </events>
      </nodeDefinition>
    </tree> I have created a custom java class to use as a data control to find out when the event is triggered. This is my code:
    public void handleEvent(Object payload){
        System.out.println("Event handler");
        System.out.println(payload);
    }When I select a record in the table, the event does not get fired.
So as a test I added my own custom method to see if contextual events are working properly so I added this method to my DC:
    public void triggerEvent(){
        System.out.println("triggering event");
    }and added it on a commandLink to the DepartmentTF. I also added an event on it:
<methodAction id="triggerEvent" RequiresUpdateModel="true"
                  Action="invokeMethod" MethodName="triggerEvent"
                  IsViewObjectMethod="false" DataControl="EmpBean"
                  InstanceName="EmpBean.dataProvider">
      <events xmlns="http://xmlns.oracle.com/adfm/contextualEvent">
        <event name="triggerEvent"
               customPayLoad="#{bindings.DepartmentId.inputValue}"/>
      </events>
    </methodAction>When I trigger this event, my event handler does get called on the employee taskflow.
So, my question is:
1) Is this normal behavior that the change row event is not triggered?
2) if yes, how do I trigger it or what is the purpose of this event?

Answer 1

I have a similar circumstance: I have a page with two regions, each region contains a table. The two tables share some information so when I update one of them
I also want the change to be reflected in the other table. I tried to use contextual events to send an event that causes one of the tables to refresh (I do not pass any payload)
but so far I have not had any success with making this work. I am wondering if the bug you mentioned here would also prevent such a setup to work? I am using Jdev 11g R1 11.1.1.6.2.
