ContentProposal on Combo - problem with Linux [message #1020704]

I have a ContentProposalAdapter I have implemented on a Combo selection box.
The combo box has a list of strings that can be selected but the ContentProposalAdapter/Provider lets the
user type a few chars and quickly cull the list down to those of interest.

For reference some ideas were gleaned from http://krishnanmohan.wordpress.com/2011/12/12/eclipse-rcp-autocompletecombotext-control

At the end of the above article, the author notes that two enter presses are needed to accept the content proposal from the key presses the user types, to get the selection event to fire. I have noticed that; but the second one does select the item for me.

We're working on the Kepler codebase; I'm developing on a Mac; A Linux (Ubuntu x86_64) developer on our project notes that even worse than requiring the two enter key presses, the second one isn't detected so the selection event never fires and he can't select an item in the Combo box.

Any ideas? The Content Proposal stuff is pretty slick, hope I can get it to work.

To see our workaround to handle this problem, see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=403704

It refers to a forum snippet with a workaround for GTK that suggests adding a traverse listener so we can override the behavior - add a Listener that handles the SWT.TRAVERSE_RETURN event to set event.doit=falst
Forum snippet is here:
