Hi Volker,
many thanks, it works now. I already tested it with the HtmlSelectOneRadio components outside of UIData, but I got runtime errors because they hadn't been found for the related HtmlRadio components. That's why I added them as children to UIData, what solved the error, but the evaluation didn't work. Using the HtmlSelectOneRadio components outside of UIData and specifying absolute IDs in the for attribute did the trick... Now I can use a table with table headers for each column, what hadn't been possible with HtmlPanelGrid.
