Hi,

I did not play with Kumpel in a long time, but from the error it seems that you get a KMProjectHistory that is not initialized properly. The referenceHistory should be self in that case, not nil.

Cheers, Doru

Hi,

I've started working with Moose with a friend and we have used Kumpel to create a model from a SVN repository and we encountered an issue when trying to create the evolution matrix. Can u help us?

One of the models we created is from the svn repository svn://svn.jdownloader.org/jdownloader without user or password.

The error we r getting when trying to create the evolution matrix is:
