Read Source from IWDCustomEvent

Question

Hello,
I have in webdynpro ABAP an action, which opening a confirmation-dialog with two Buttons "yes" / "no".
I can check in wdEvent from the action of destination, which button clicked.
For Example: wd_Event->getParameter("ID"). The returnValue ist btn_yes, if clicked "Yes" and btn_no, if clicked "No". The issue is, I can use the same action for Yes and No and check with an abstract function the ButtonID.
Now, I'm search the same function in Webdynpro JAVA.
How I can get the called ID from com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent in an action?
IWDCustomEvent has a few getter (getString(""), getObject("")...). But I don't know the name of the getter-parameter for the ID.
Or, how I can open the confirmation dialog with a parameter and get it in the event?
I hope, your have a nice answer.
Regards
Maik

Answer 1

you have to rethink your approach on Java
you gonna have a save button with the method save that only opens the confirmation window
public void onActionSave(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent ){
     IWDConfirmationDialog window = wdComponentAPI.getWindowManager().createConfirmationWindow  ("Save it?", wdThis.WD_EVENTHANDLER_ON_CANCEL, "Cancel");
    window.addChoice(wdThis.WD_EVENTHANDLER_ON_SAVE, "OK");
    window.open(); ///..or show
then you have two other methods (event handlers): onSave and on Cancel:
public void onSave(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent ){
   save();
public void onCancel(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent ){
   //do other stuff
about your solution, I think this:
onActionSave(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
is not this:
wdThis.WD_EVENTHANDLER_ON_SAVE,
I think it would be:
wdThis.WD_EVENTHANDLER_ON_ACTION_SAVE,
...also print the wdEvent.getName() to see whats there
