Dimension could not be opened in Performance Modeler

[andre lie]

Hi all,

I have a few dimensions created using Perspectives. Then I opened the dimensions in Performance Modeler (and possibly did some changes like adding elements, etc). Somehow the dimensions could not be opened again in Performance Modeler. I got this error message: Could not open the editor: An unexpected exception was thrown

However, I could still open the dimensions in Perspectives.

Anyone has experienced the same issue?

Thanks
Andre
