Exaclty. The current implementation works for non-AJAX forms.

I was thinking further about this. For the AJAX mode, we need 
implemented a handler manager.

One version:
Every widget can have a method with a predefined name, then in AJAX 
mode, before commiting, the AJAX controller call this methods. We don't 
need a stack. Only a boolean indicator to keep track that the user 
already pressed a button on the page.

Another version is:
We have an stack (as we have now). But every item on the stack contains 
also the widget name to keep track of them. In AJAX mode, when the 
response comes back from the server, the AJAX controller only delete the 
methods in the stack for the widget that comes in the response. The will 
keep the methods for all the no changed widgets. That way they will be 
executed in the next submit event.

Also I will like to get rid of the "generate-id()" call in the XSLT. 
They simply don't work for AJAX.

Good idea.
