Hi Guys,
So i've been battling with this error since yesterday and it seems not to be going anywhere. I really need help with this.
Anytime i open an EMF model editor from epsilon, i get the following error. I think the problem is coming from the property view. Because when i try to create an instance of my emf metamodel using the EMF model editor from epsilon i'm not able to edit the properties from the property view. The it throws the below exception and the property view is empty.
Even if i open and EMF model from the epsilon provided examples (e.g. the tree.model in the etl examples folder) i get this exception.
It was working previously and all of a sudden this problem started.
I'm guessing the problem is coming from the exceed editor so i uninstalled and reinstalled the Epsilon Development Tools for EMF feature but the problem still remains.

Error log below, thanks a lot.

Hi,

It's hard to tell what may be going wrong here - particularly given that this worked fine for you on a clean setup. Would it be an option to download a fresh copy of the Epsilon distribution and import your projects there?

Cheers,
Dimitris

I'm using the Model Transformation Chain(MTC) Flow to do a source code to source code transformation. So my eclipse installation has various tools including Epsilon. It will take some time to re-install everything all over again but i guess i might not have any option but to do this.
Anyway thanks a lot for all your quick responses. I appreciate them.

Hi,

While you're rebuilding your Eclipse installation it may be worth trying Exeed after each installation step to see if you can identify which tool appears to be interfering with it, and let us know so that we can investigate.

Cheers,
Dimitris
