Is EMF generated code just for plugins? [message #512058] Wed, 03 February 2010 18:34 Go to next message

I wrote my own viewer/editor to try and take advantage of the EMF generated code. I wrote it as a straight Java application (not a plugin; it has a main). It runs, but it gets an error popup window when it runs that says:

"Workbench has not been created yet"

Is the generated code intended just for plugins, or am I doing something wrong?

Thanks,

It depends on which parts of EMF certainly EMF's runtime and Edit
framework work stand alone. All of the framework works with RCP without
a workspace. So it's not clear what's causing your message. It seems it
must be some other part, not EMF.

Can this help point me in the right direction? It seems as if the code is looking for an image of some kind, and it is trying to get it from the Workbench?

Oh, I just remembered that you said this may not be an EMF problem. Can you point me to the correct forum?

Thanks,

Herb,

It sounds like you're displaying Resource instances; in this code we're
trying to look up the same icon as would be used showing the IResource
in the IDE. I suppose we could add a catch clause and just use a
default resource image for this case. If you open a bugzilla, I'll add
such a guard for EMF 2.6. As a workaround you could specialize
ResourceItemProvider's getImage to avoid this problem.
