Select + FreeFormDelegate + Filtering

I am at a loss

I have a select that uses free form delegate returning 2 to 3 hundred results. When I filter on select down to a couple results and select 1 everything works fine and event source contains the itemId of what was selected. When I filter down to a single result and select it using the keyboard or the mouse the event contains source=null

Vaadin 6.8.5

Any suggestions on where to look would be greatly appreciated

– Update ( Still no solution )
It’s always the first item that comes back source = null in the event

– Update #2 Known or atleast seen by others http://dev.vaadin.com/ticket/10195
