Closing the form doesn't trigger evaluation

[agermosh]

I implemented the form to parametrize the class skill and it is working ok
with one exception - after done editing and closing the form with "ok"
button evaluation cycle is not started. So, all parameters controlled by
form are changed as expected (I see new values in debug window),
but derivatives, calculated by ability evaluation scripts remain the same.
If I trigger the evaluation by changing any other thing (like reducing the
ability) scripts are working ok.
Any suggestions?
