tabbedPane style problem

[Igor devor]

Hi,
 
    When I set activeTabStyleClass, inactiveTabStyleClass,
activeSubStyleClass, inactiveSubStyleClass, or tabContentStyleClass
 on a t:panelTabbedPane, the style doesn't applies to the pane.
For exemple on tabContentStyleClass="someStyleClass" we have this in HTML
generated code :
 
 class="myFaces_panelTabbedPane_pane someStyleClass"

It is a bug ? Or the browser merge the two class ?
How can we override some style properties ?

I use tomahawk 1.1.3 and myface 1.1.3

Thanks,
Igor
