TypeError: 'undefined' is not an object (2.0.0 build 341)

I'm getting this by:

a. Loading a project (and doing nothing else)
b. Saving the project after it has loaded

2.0.0. build 341
OSX Lion 10.7.3

Is there anything I can look into to figure out what the offender might be? A bit harrowing, as I'd entrusted the creation of a soon-to-hit-production app to the designer (despite the warnings of course, which I understand).

Thanks guys.

Yes, I love how we tell everyone do NOT use this for production; it's a beta yet everyone does

We have a critical bug in 341 regarding the config pane being filtered and changes occurring that can cause this error. The next build will resolve this problem that many are encountering.

Hey man, I put my disclaimer in!

It's flattery when you think of it! Have used Ext since day one back when Jack was fresh off YUI, never been let down. I'm sure you guys will figure it out. I've resorted to hand-bombing the code, it's quicker, but the GUI makes me happy.

Cheers, thanks for taking the time to respond.
