on both 7.0 and 7.0.1 BOS community studio, when trying to create a Validator on a form or a field, using a Groovy expression, the following error occurs:
"An error has occurred. See error log for more details.
org.eclipse.ui.part.FileEditorInput cannot be cast to org.eclipse.emf.ecore.EObject"
I've tried the Studio on several machines with the same results.
The error does not happen in Studio v6.5.1
Seems like a bug.
Java version: 1.8.0_31
Error stack and configuration follows:
