Menu Contribution appears multiple times on restart [message #892450]

Hello,

I have written a plugin that adds a menu item to my main plugin (via model contribution, model fragment)

When i start the application for the first time (new workspace), the new menu item is inserted correctly, but when i start the application again, the menu item gets insterted again. With each start the Item gets inserted one more time.

When i look at the "workbench.xmi", I see that with each start the menu item is inserted once more.

To reproduce my problem I attached a file containing 2 plugins and the feature containing both. When you run the product more than once without cleaning the workspace, the menu Item ist inserted multiple times.

Any help would be greatly appreciated.
Thanks
Marc

Thanks for the info.
But in my case I contribute the model elements (in this case the menu item) via a static model fragment and the extension point org.eclipse.e4.worbench.model without any java code (so far)
Shouldnt the framework realize, that the model fragment is already present in the saved application model and not add it again.
Otherwise where would be the benefit of contributing to the application model via a model fragment, when i have to delete the contributed elements manually when the application exits.

Perhaps i am missing something really obvious (like some "contribute only once" setting)
