Default Button problems on a Composite in Juno [message #987717]

Wise and powerful Eclipse folks, I have a strange situation that didn't show up in Indigo but seems to in Juno.

We have a tabbed property page with two parts. On one side we have a list with a Remove button and on the other we have a composite that changes based on what's selected in the list. Each composite has a collection of fields - Text, Combo, Button, etc.

The problem is that if I hit Enter on one of the fields on the child composite, the button further up the hierarchy on the other side is getting a selection event triggered. The user didn't click the button and this is causing no end of problems.

Is there a way to disable that default key handler in particular contexts? On a separate property sheet with no child composite we have two buttons and a list and no matter where you are on the sheet if you hit Enter, it triggers the first button. So I suspect there's a default at work here I'm not seeing.

I tried setting the shell's default to null (shell.setDefaultButton(null)) but that doesn't seem to do the trick.

Any suggestions? I know it's sort of like a needle in a haystack without code, but this seems to be a problem across the board with all of our tabbed property pages regardless of how complex they are.

Thanks in advance oh wise and powerful Eclipse gurus...

If it helps at all, this is a stack trace. I've tried circumventing the key event, but nothing I've tried has worked so far. There has to be some listener working above me in the framework intercepting key events regardless of the context.

Obviously if the user clicks the button or hits Enter, I want the event to fire. But the event in this case has nothing to do with the button.
