Description Peter Kullmann

I'm trying to generate code from an *.ecore file. This does nothing (doesn't even show an error message). The following exception is logged:

My setup is a Eclipse SDK 3.6.2 with Texo 0.1.0.v201104071256.

Hi Peter,
I know that mwe has changed its api in a later release (after 3.6.1), can you list the mwe plugin versions?

It is a topic I want to cover when making Texo available for Indigo (3.7).

gr. Martin

Comment 2 Peter Kullmann

Hi Martin,
My mwe plugins are:
- org.eclipse.emf.mwe.core 1.1.0.v201103160530
- org.eclipse.emf.mwe2.runtime 2.0.0.v201103160530

Can you give me a workaround for the problem, please?

Comment 3 Martin Taal

I have no workaround at the moment (other than downgrading to a previous version of mwe)... 
I will try to work on this this weekend.

gr. Martin

How can I downgrade to a previous version of mwe? Older plugins do exist in my plugins folder but I assume I cannot just delete the offending version... I guess I wait for next week. Thanks for taking care of it.

This has been solved in the latest build of Texo (published a few mins back)

Works great. Thanks.
