ComboViewer not nullable? [message #506921]

Dear all!

I already posted this on the JFace group, but did not get much response. Maybe this is a RAP issue. I'm looking for a way to reset a read only ComboViewer. Once an item was selected I cannot deselect it.

Combo.setSelection(StructuredSelection.EMPTY)

Did not work. Neither all other variations. Even if I delete all items from the Combo, the last selected item is still displayed (though it is not in the selection list any more).

Did anybody try this in a RAP application? It looks kind of strange to me that there is no method to set a ComboViewer to null.

Thanks for any help
