merry christmas everyone!

i got a problem where i didn´t find a solution or a hint in the manual or the forum, but it seems like quite a common issue to me

when i use a4j:support in an item that uses an javascript event, either the js or the a4j does not work, like here:

<h:column>
<h:selectBooleanCheckbox value="#{ptn.selected}" onclick="return dataTableSelectOne(this);">
<a4j:support event="onselect" action="#{kuvptnsearch.dummy}" reRender="ptnSearchButtons"/>
</h:selectBooleanCheckbox>
</h:column>

the onclick is called, die onselect rerendering does not happen. if i turn events around and use onselect on the checkbox-tag and onclick on the a4j:support it is the other way round?! what am i doing wrong? can anyone please help?

thanks and kind regards,
herbert
