selection and deselection in treeviewer [message #875276]

When I change a selection in a treeviewer, it appears to have two selection events, one for the deselected item and the other for selected item, in that order.
This is not at all desirable at some times, especially if it involves making server calls. Is there anyway to avoid the first selection event i.e. event from deselection?

Thanks for your help!

SWT's Tree does not send selection events for event deselections, so
they must be originating in the TreeViewer. You should ask this on the
JFace forum since TreeViewer comes from JFace.
