Hi,

I am not sure if this is the right forum but let's try.

I have implemented some functionality that is executed from top menu bar. These actions are triggered by handlers. For example, this is the way I have defined the actions in plugin.xml and they are working nicely:

  <extension
         point="org.eclipse.ui.handlers">
      <handler
            commandId="org.eclipse.papyrus.myCommands.myCommand"
            class="org.eclipse.papyrus.myHandlers.myHandler">
      </handler>
   </extension>

I'd like to execute the same functionality from context popup menu, so I created an entry like this:

	<extension point="org.eclipse.ui.popupMenus">
   	   <objectContribution
            adaptable="false"
            id="org.eclipse.papyrus.mymenus.mypopupmenu"
            objectClass="org.eclipse.gmf.runtime.diagram.ui.editparts.ShapeEditPart">
         <menu 
            id="mypopup" 
            label="&amp;My Menu" 
            path="additions"> 
            <separator name="group1"/>
         </menu>
          <action
               class="org.eclipse.papyrus.ossli.myActions.myAction"
               definitionId="org.eclipse.papyrus.myCommands.myCommand"
               enablesFor="1"
               id="org.eclipse.papyrus.ossli.menus.myPopupaction"
               label="&amp;My Action"
               menubarPath="mypopup/group1">
         </action>
      </objectContribution>        
	</extension>

This works fine and the runWithEvent-method from myAction is executed. myAction implements IActionDelegate2.

1. Is there a way to execute a handler straight from popupMenu extension point?

2. If not. How can I generate an ExecutionEvent needed by the myHandler's (implements AbstactHandler) execute-method as a parameter?

I am using Papyrus if it matters.

I managed to do the second approach. ExecutionEvent's constructor just wants some parameters that are not important for the functionality, so I made a map of temporary parameters and passed them there.

You could also use the "menus" extension point rather than "popupMenus", referencing your command id.
