Log with NPE trace

We have an xtext grammer that compiles and runs without errors (attached).  When editing the file, it starts off working OK and then NPEs eventually on a CTRL+SPACE.

File that we're editing

To cause the NPE, I just opened this file, added a ',' after
HandledMenuItem "exit" {
command exit
type Push
}
and hit CTRL+SPACE (I expect to see more choices like HandledMenuItem, Menu_Impl, etc.

Paul, could you please attach the version of UIElements.ecore that you used?

The ecore model that we used

This is the ecore model that we used for this. We didn't use a modified, intermediary one like you guys did for your demo at last year's eclipsecon.

I cannot reproduce this bug with Xtext 2.0. What I tried is:

HandledMenuItem "exit" {
command exit
type Push
}, |

Invoke CA at cursor position | and I got DirectMenuItem, HandledMenuItem, Menu and a bunch of other things that looked good to me.

Please reopen if the problem is still reproducable for you with Xtext 2.0.
