### Listbox Listener:onCheckSelectAll and onSelect - Problem with double event

Hi,

I use 2 Listener on a Listbox. The the onSelect Listener tells me when a row was selected. And the onCheckSelectAll is fired when the checkAll (multiple=true) checkbox is triggert.

The Problem is now, if you trigger the checkAll combonent, then first the onSelect Event is still triggert, and after this the onCheck event from the onCheckSelectAll. This produce for the first row a double select/unselect in my case.

So how I can fix this?

Regards.
