So .... do you have a reference to an object with a null id?

Why not put a break point just before the assertion and have a look at exactly why the assertion fails...

i will do that.

but, i am not getting this failure when i switch to 2.0.3. it is exactly the same application.

everything works fine with 2.0.3
