Hello Bjoern

I am using the BEANMETHODINVOKER in a WORKPAGE inside a WORKPLACE. When I close (see picture) the WORKPAGE then I am receiving errors.

Do I misunderstand something?

Thank you for your help in advance
PATRICK

JSP snippet

Code:
 <t:beanprocessing id="g_1" >
 <t:beanmethodinvoker id="g_2" actionListener="#{d.GruppeBearbeitenUI.onInvokeEnd}" jsfphase="invokeEnd" />
 </t:beanprocessing>


JAVA snippet
Code:
   public void onInvokeEnd(ActionEvent event)
   {
   }

Hi Patrick,

what is your intention, do you want to react on the close workpage event?
Maybe there's another way to realize that?

I have no intension. I already got my stuff that I expected from the invoker method. In practice my method looks like this and works fine...

Code:
   /**
    * Show hidden form again
    * 
    * @param event
    */
   public void onInvokeEnd(ActionEvent event)
   {
     if (getWorkpageContainer().getCurrentWorkpage() != null)
     {
       m_shownAfterHiddenWorkpageId = getWorkpageContainer()
       .getCurrentWorkpage().getId();
       if (m_fieldEditedOrValueChanged)
       {
         getWorkpageContainer().switchToWorkpage(
         getWorkpageContainer().getWorkpageForId(getPageName()));
       }
     }
   }


Also all my defined WorkpageDefaultLifecycleListeners are working fine. What I would like to say is: If a BEANMETHODINVOKER is defined in a JSP and when I close my WORKPAGE then I get errors.

But maybe you are right, if there exists a way to avoid using any BEANMETHODINVOKER would be great.

Prehistory:

I have a WorkpageDefaultLifecycleListener with an overridden reactOnHiddenInContentArea() method defined.

Scenario:

1. One WORKPLACE with many WORKPAGES is open (see picture again).
2. The user switches to a different WORKPAGE than the already active one (lets name this PREV-WORKPAGE).
3. Desired WORKPAGE got visible and reactOnHiddenInContentArea() was kicked off.
4. reactOnHiddenInContentArea() should tell the user that he first must complete things in PREV-WORKPAGE before switching to another WORKPAGE.
4.1. reactOnHiddenInContentArea() should switch back to PREV-WORKPAGE.

To achieve step 4.1 I had to use the BEANMETHODINVOKER which runs onInvokeEnd() after reactOnHiddenInContentArea(). Trying to do the step 4.1 direct in reactOnHiddenInContentArea() will not work.

Hopefully you can help

Thanks and with best regards
PATRICK

Hi,

sorry for the delayed feedback. I understand your intention, I'll try to reproduce your scenario and look for a possible workaround

Hi,

a possible workaround could be, to implement the listener in the managed bean to react explicitly on the close event, in the close event you make your checks if data is persisted and consistence.

Maybe you have to introduce a kind of dirty flag, which shows the state of the data. Every data manipulation (setters) set the flag to true, save method clears the flag!

When switching or closing you check the dirty flag?
