Thanks to both of you. That did the trick. I have now two RadioButtons within
the RadioGroup. One of them inside the loop and one outside owning different
id's but same name. Now it is working as expected.
again thanks for the quick response
Jens
No, Tapestry will give different ids to your radio tags inside the loop.
In the HTML page, a radio belongs to a radiogroup if it has the same
"name" parameter, not the same "id". And Tapestry will give a different
id but the same "name" to each radio you put in a radiogroup wether it
is in a loop or not.
