Hi,

I get this exception for a little while, but never needed to use any persisted state. But now, I want to use the getPersistedState-method of parts. Unfortunately the workbench.xmi isn't created correctly. Anyway it fails to load with the following exception:

The RCP has one main Application.e4xmi and about eight fragments with one perspective per fragment.

I added the workbench.xmi to this post. I'd be really glad to get a hint on that.

Best regards
Bastian

Ok... Found it. It was my bad. copied the fragments and didn't change the xmi:id fields.

Sorry Smile

I'm sorry, but although I found out what I did wrong, I still won't get the workbench.xmi to be loaded correctly.
If the application starts the first time (and no workbench.xmi is available) all fragments are included. Then I exit the RCP and the workbench.xmi gets written. When I restart the app the following error occurs:

This seems to happen, since the xmi:id's ind the workbench.xmi are different from the xmi:id's in the Application.e4xmi. The id's from the included fragments are the same as in the workbench.xmi.

So my question is: How can it happen that there are different id's used in the workbench.xmi than in the Application.e4xmi?

Best regards and thanks for help
Bastian

We are experiencing a similar exception in Eclipse 4.2 extended by Rational Developer for i v 9.0

From the .log:

Very interested in updates as customer is pushing for resolution.

Hi Edmund,

I don't know what causes the exception, but your elementId seems odd to me. It doesn't look like an elementId, more like a Java Object. Does this elementId get set manually?

Best regards
Bastian

The scenario is that the customer is trying to customize a perspective, and then when they load the workbench, their customizations are lost due to the exception.
So the elementId is being set by the Customize Perspective ... action in Eclipse 4.2
