PloneFormGen: Disable radio-button when a certain condition is met

Question

I want to create a dynamic form in a Plone 4.3 site with PloneFormGen 1.7.15. Dynamic means that I want to disable an option, when a certain number of participants have chosen this option.

Is it possible the set the attribute "disabled" to a radio button? I have not found a way to do it manually.
I was looking at the article How can I generate a registration number in PloneFormGen, using a TALES Expression? which show how to implement a counter. But I have no idea, how to actually change the radio button, when the condition is met. Any hints on that?

I don't have a real answer for you and maybe I'm offtopic, but if you are implementing an engine to subscribe to events you can evaluate the usage of http://plone.org/products/collective.signupsheet which user PloneFormGen but handle number of free slots. — keul, Aug 05 '14 at 15:35
I don't have time to write a full answer but you should be able to do a custom expression for a radio button vocabulary options. With this, you can check your property for tracking participants. — vangheem, Aug 06 '14 at 03:14

I used http://plone.org/products/collective.signupsheet for the form. It has the functionality to limit the number of registrants for an event. The solution I thought of when asking the question became obsolete.
