rich:tooltip in rich:tab (label facet) -> JS error 'this.toolTip.style' is null or not an object

[tabeadierk]

Hi,

i want to use rich:tooltip in the Label of a rich:tab.

While switching the tab, i sometimes get an Javascript error "this.tooltip.style" is null or not an object.

I am using Richfaces 3.3.3.Final and IE8.

I have attached my code in File "details_user_tab.txt"

Can anyone please help me.

Thanks,

Tabea
