Hi all,

I tried to run a working RCP product on e4, just for the fun.
To achieve this, I use e4 0.9 as target platform, and I create a new product definition that includes all e4 things.

Then, when executing the product, I get while loading the workbench:

I tried to remove the org.eclipse.e4.ui.workbench.fragment, but I still get this error.

How can I get rid of this error and run my product? Is this a bug in e4, should I open an issue on bugzilla for it?

You can open a bug at https://bugs.eclipse.org/bugs/enter_bug.cgi?product=E4&c omponent=UI

What ID is it looking for when you hit the NPE:
at org.eclipse.e4.workbench.ui.menus.MenuHelper.indexForId(Menu Helper.java:126)

Does your RCP app have actionSets that depend on menus from other actionSets? Or is it looking for something contributed by your ApplicationActionBarAdvisor when it NPEs?
