Change label of UIElement when command handler is disabled [message #335853]

Hello together,

I have the following situation with our RCP application based on eclipse
3.3:

- I contributed a command without a default handler
- I added a menu contribution for this command -> displaying the standard
label "New"

- Now I have several handlers for the command which get activated
depending on the currently active perspective. They all implement
IElementUpdater and set their specific label ("New A", "New B") to the
UIElement.

My problem is:

When the handlers are deactivated again, the label is not reset to the
initial default "New". How can I realize this behavior?

In 3.3 you would need to provide a default handler that returns
isEnabled()==false and set the text to "New"

You might want to open an enhancement request at
