Hi Ralf,
thanks, that pointed me in the right direction. Works like expected.
You're welcome of course :-)
Now I still have the little problem, that I want to grey out the label
around the disabled radio button. From the code I guess its impossible
to add a special css class for these label tags without hacking the code
or extending the Zend_View_Helper_FormRadio class myself.
It doesn't seem so. It's not documented either, so I think it would be
quite a valid issue to report and propose a patch for in the issue
tracker. Maybe something like labelClassDisabled as a helper option
might be appropriate.
