Mars Version: Problems with Dynamic menu contribution

Question

I create an "Eclipse 4 Application project" called test with Luna and Mars version.
In my Application I add a Dynamic Menu Item called ToTo with the following code:
Quote:
package test.handlers;
import java.util.Date;
import java.util.List;
import org.eclipse.e4.ui.di.AboutToShow;
import org.eclipse.e4.ui.di.AboutToHide;
import org.eclipse.e4.ui.model.application.ui.menu.MDirectMenuItem;
import org.eclipse.e4.ui.model.application.ui.menu.MMenuElement;
import org.eclipse.e4.ui.model.application.ui.menu.MMenuFactory;
public class Toto {
@AboutToShow
public void aboutToShow(List<MMenuElement> items) {
MDirectMenuItem dynamicItem = MMenuFactory.INSTANCE.createDirectMenuItem();
dynamicItem.setLabel("Dynamic Menu Item (" + new Date() + ")");
dynamicItem.setContributorURI("platform:/test/");
dynamicItem.setContributionURI("bundleclass://test/test.handlers.DirectMenu");
items.add(dynamicItem);
@AboutToHide
public void aboutToHide(List<MMenuElement> items) {
And the following code for the DirectMenu:
Quote:
package test.handlers;
import org.eclipse.e4.core.di.annotations.Execute;
public class DirectMenu {
@Execute
public void execute() {
System.out.println("Direct Menu Item selected");
With Luna version when I click on the menu Item I have the date and the execute part is OK
With Mars the item is here with the date, but when I click the execute is never executed?????
Can you help me!!!
Regards
Antonio

You would need to copy the MenuManagerRenderer code to a local class and use the patched MenuManagerHideProcessor in that class. Than register the modified MenuManagerRenderer in the context so it is used instead of the default one.
So you need to get the code of MenuManagerRenderer out of the platform code, then the MenuManagerHideProcessor from Gerrit and you need to know how to replace the renderer. For the last there should be a tutorial by Lars Vogel somewhere.
Of course you should also vote for the posted ticket, to increase the visibility.
Hello Dirk,
could you please describe in more detail a way how to get this workaround working on Mars? Matt Biggs mentioned similar thing in bug report id=469581 but I don't know how to make it work.
I've created a class called MenuManagerHideProcessor with a patch from git. I don't know how to do second part (registration). I read Lars article about renderers at vogella page. (Eclipse4Renderer) and found a property "CUSTOM_RENDERER_URI". I did following in @AboutToShow method:
MDirectMenuItem directMenuItem = MMenuFactory.INSTANCE.createDirectMenuItem();
directMenuItem.getPersistedState().put("CUSTOM_RENDERER_URI", MENU_MANAGER_URI);
directMenuItem.setLabel(view.getLabel());
directMenuItem.setContributionURI(SHOW_HANDLER);
It seems that this is not the way how it should be done.
Thank You for any insights
PS: Sorry I couldn't post a direct links to bug tracker and vogella site because of "You can only use links to eclipse.org sites while you have fewer than 5 messages".
