Hi Matthias, just an idea, may work or not, but worth a try imho:
put the HtmlSelectOneRadio component(s) somewhere out of the uidata (e.g. as child of viewRoot) and set a id, also set a id to all parent namingcontainers. in the for attribute of the HtmlRadio components use a absolute id (e.g. ":[id_of_viewRoot]:[id_of_HtmlSelectOneRadio]", if HtmlSelectOneRadio is on top level). Not sure if this will work, but after a short look into HtmlRadioRenderer.java and implementation of findComponent() i think this could work.
