ADF : Refresh the parent view when a taskflow displayed in a popup returns

- Refreshing the parent view when an in-line popup taskflow returns.

This scenario usually arises when the second task flow updates tables used by the first one from a different transaction context. 

There are two taskflows, both work with separate transaction contexts(Transaction attribute is set as new-transaction). Second taskflow is invoked from the first one as a dialog. The requirement here is to refresh the 'executables' of calling page(from first taskflow) when the second taskflow returns. 

createWO view from first task flow.

truckCompTF is the second taskflow.


- Define a returnListener for secondary window on the command button (which invokes second taskflow as dialog)

- Create method as dialogReturnListener in returnListner and copy below code

    public void dialogReturnListener(ReturnEvent returnEvent) {
        BindingContext bc = BindingContext.getCurrent();
          DCBindingContainer dcb =
            (DCBindingContainer)bc.getCurrentBindingsEntry();
          DCIteratorBinding iter =
            dcb.findIteratorBinding("TransportUnitVOIterator");   //your VOIterator 
          iter.executeQuery();         // It refresh the underlying IteratorBindings used by the parent page. 
       RequestContext.getCurrentInstance().addPartialTarget(returnEvent.getComponent().getParent().getParent());

    }
