Somehow I've gotten a lexical error in my transformation. however, I cannot edit it. I double click on the transformation or the error in the log and can never get to the ability to 'edit' the transformation.

This is JBoss DV 7.1.1 ga and Teiid Designer8.5.0.Final

Nor sure what else you may need but here's the event details:

I also get this stack sometimes:
