access attributes of rendered submit button of t:panelTab

["Schaal, Roland" <R....@Verband.Creditreform.de>]

Hello,
 
what I wanted to do is to add an onClick-Method to the rendered
submit-button of a panelTabbedPane.
 
I thought the <t:panelTab> would be the right place to add the
onClick-Method because with this tag you also specify the name of the
button in the label-attribute. But instead of adding the specified
onClick-Method to the button he adds it to the rendered table of the
panelTab.
 
Can somebody give me a hint how to achive this?
 
Chears,
Roland
