I dont know if you can help with this one but when I set one of my properties as disabled, it seemed to cause one of my contributed action methods not to be able to be executed. i.e Hitting the OK button did not actually execute the method.
My break point was not getting hit.
I checked that I had no inconsistencies in the code with Choices methods etc.
Can you help me debug this?
Where would I debug this in the framework for my benefit?
