Problem with a4j:support in dataTable header facet
Hi
I have a strange problem where a h:selectBooleanCheckbox with a4j:support attached is not updating the backing bean when inserted in a header facet. The same call made from check boxes within the table's cells or elsewhere on the form works.
Refer to the check box "header_check" in the listing below - that is not working, although the check box "line_check" within the table works and calls the backing bean method.
Help much appreciated
