[FNR] TreePanel with checkboxes CheckChangedListener returns null

[maqjav]

Hello.

I just updated to GXT 2.2 beta and I found a bug with TreePanel.

TreePanel<BeanModel> tree= new TreePanel<BeanModel>(storeAtributes);  
tree.setDisplayProperty("name");
tree.setCheckable(true); 
tree.addCheckListener(new CheckChangedListener<BeanModel>() {  

         public void checkChanged(CheckChangedEvent<BeanModel> event) {  
	        for (BeanModel bean : event.getCheckedSelection()) {
		      // do something
		}
});

If I click on a checkbox the event is fired and event.getCheckedSelection always returns null.
This function was working perfectly before, but now it's not.

Thanks.
