BTW: With JSP, I only had a selectBooleanCheckbox in a column of the dataTable. It had a component binding and I could access it after setting the rowIndex of UIData.
In my current case, I need multiple radiobuttons (HtmlRadio components) in each row, aligned with the column headers. If I would use only one HtmlSelectOneRadio component for all rows, and access it by using UIData, what should I set the HtmlRadio components "for" attribute to? I have only one HtmlSelectOneRadio component. Can you imagine that it would work if the HtmlRadio components of all rows refer the same HtmlSelectOneRadio component?
