> On rich:tab we use the attribute "onheadermousedown" which a javascript function defined by a4j:jsFunction. When we switch tab, we got the following error:
> {code}
> item is undefined - Line 363
>    /**

>    * */
>    __getItemIndex : function (itemName) {
>    var item;
>    for (var i = 0; i < this.items.length; i++) {
>       item = this.items[i];
> >>>>>  if (!item.disabled && item.getName() === itemName) {
>          return i;
>       }
>    }
> rf.log.info("TogglePanel.getItemIndex: item with name '" + itemName + "' not found");
> return -1; }, 
> {code}
> The error may be linked to the RF-11763.
