ComboViewer not nullable? [message #503889]

Dear all!

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).

BTW: I use Eclipse RAP. I hope it's not a RAP bug. Did anybody try this in a RCP application? It looks kind of strange to me that there is no method to set a ComboViewer to null.

Thanks for any help

If what you want is just to reset the selection you can do:

  combo.setText("");
  combo.deselectAll();
