id of radio button not unique when SelectItemGroup is used

Hello everyone,

For HTML labels to work properly the IDs of the radio buttons should be unique, but when a SelectItemGroup is used to group radio buttons the ids are not unique.

The generated HTML code is pasted below, as you can see the radio button id "j_id_jsp_1265752901_2:j_id_jsp_1265752901_4:0" and "j_id_jsp_1265752901_2:j_id_jsp_1265752901_4:1" are used twice on this page, which invalidates the HTML and breaks the labels.

I'm using the most recent version of MyFaces (1.2.7), running in Tomcat 6.

Does anyone know a fix for this? I wouldn't mind having to generate an ID for all radio buttons myself, but I can't figure out how without modifying the renderer.

Thanks for your time,
Eddy
