org.eclipse.ui.edit.copy NotHandledException [message #485358]

Hi,

Eclipse 3.4.2/linux

I've included the org.eclipse.ui.edit.copy action in my application, and
supplied my own handler, which is working fine. However, I'm having
problems when the default handler (WidgetMethodHandler) is used. The
copy action in the Edit menu is always enabled, whenever this handler is
being used, regardless of whether or not the handler's isHandled()
evaluates to true.

When the copy command is executed, the isHandled() is checked, returns
false, so the handler isn't used and a NotHandledException is thrown.

This behaviour can be reproduced in eclipse 3.4.2/linux via the
following actions:

Open a plugin.xml editor, select the overview tab, in the outline view
select "overview", in the Edit menu select copy, check the error log.

I've tried to reproduce this on eclipse 3.5/windows/linux and it doesn't
seem to happen (although I've not debugged to find out why).

Is this a 3.4.2 bug? Is there a workaround?

Thanks in advance,

Stew

See the discussion in http://www.eclipse.org/forums/index.php?t=msg&th=153761

In 3.4.x only part of the ActionFactory actions were converted to commands. Any ActionFactory actions that return RetargetActions need to be replaced with CommandContributionItems.

Thanks for the response Paul. I incorrectly indicated in my original
post that I was using the copy action in my application. I'm actually
using the org.eclipse.ui.edit.copy command (adding the command using the
org.eclipse.ui.menus extension point). I tried out the solution you
posted in the linked thread but got exactly the same result. I'm
guessing these are two ways of achieving the same thing?
