I'm writing a plugin (for RCP applications), and I need to launch two
different versions of a wizard, depending on whether the workspace
(org.eclipse.core.resources) bundle is available. Currently, my setup is:
com.example - defines view, a basic wizard, a command and a handler that
launches the basic wizard
com.example.resources - defines a more advanced resource-aware wizard, and a
handler that launches it
The goal is to be able to use the first plug-in stand alone, and drop in the
second if the RCP application uses the workspace and wants the added
functionality.
I have been investigating the activeWhen condition for handlers and have
succeeded by creating a dummy property tester and adding it to the
enablement condition in the com.example.resources handler. It seems that a
condition with "and(A, B)" gets higher priority than "A" by itself, even if
"B" is a dummy test.
I am wondering if this is a valid/supported approach or if there are better
ways to do this. Is there a way to add a simple true branch in a condition
that would avoid the property tester?
Thanks,
Will

I spoke to soon - this does NOT work. I was looking at the wrong thing and
upon further investigation the two handlers do still conflict. So I do not
have a solution and would appreciate any suggestions.
Thanks,
