Hi,

I noticed some strange behaviour with running my Eclipse 4 application on Kepler M4 platform. If the HandledMenuItems are connected to a CommandHandler, they will always show up disabled. This is not true if the application is executed with a 4.2 platform.

First I thought this is related to using Core Expression visibility rules. But it seems this is also true if I don't use them. I'm not sure why this happens and I opened a ticket for this. I even attached an example.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=399657

Can anybody confirm this bug or at least give me a hint what is wrong? If this happends because of some plugins?

Thanks in advance,
Dirk

Hi Dirk

You're right. I don't not the state of this bug, but if you start the wizard to create the E4 Application there is an addon missing:

  <addons xmi:id="_e3mMgGR5EeKSBuqN6T0XkQ" elementId="org.eclipse.e4.ui.workbench.handler.model" contributionURI="bundleclass://org.eclipse.e4.ui.workbench/org.eclipse.e4.ui.internal.workbench.addons.HandlerProcessingAddon"/>


jut add this one to your Application.e4xmi and it works.

Thanks Beat for answering. Sopot answered in the bug directly with the same information.

Adding the org.eclipse.e4.ui.internal.workbench.addons.HandlerProcessingAddon to the addons of my application solved the issue.
