Comment 1 Justin Spadea CLA 2011-05-09 18:34:15 EDT 
Disregard the stacktrace above, I double-clicked the wrong entry in the Error Log view. Here's the correct stack trace, which is an NPE not CCE:

java.lang.NullPointerException

Comment 3 Justin Spadea CLA 2011-07-19 14:02:34 EDT 
Added code to handle cases when the form is not nested inside a formgroup in:

Egl2MofBase.java
Egl2MofExpression.java
FormImpl.java
