"The operation is not currently available" [message #325539]

I created a plugin project and executed the extension wizard "Hello,
World action set" to get a simple menu action.
When I launch the application instance and press the sample action
button, I get a dialog that says "The operation is not currently
available". I can't debug this.

What is wrong here?

This happens when the system can't load your action or things it is
disabled after loading the IActionDelegate.

Do you ever set anything to disabled in your IActionDelegate? If not,
does your plugin that contributes the ActionSet have itself set to be
singleton:=true and lazy start = true?

This usually happens when the class name specified in the plugin.xml is
not found. You might have refactored the class/package name or modified
the plugin.xml

I encountered this when I was trying to execute an action from within the
right-mouse-button menu (popup menu) of the package explorer. Hitting the
button in the toolbar worked fine. After a while I found out, that the
Action needs to implement the IWorkbenchWindowActionDelegate interface to
be able to get triggered from the RMB menu. Maybe you find this helpful.

Kind Regards

Thomas

I have just seen this with a plugin compiled for a newer Java than the
one that was running eclipse.

That has been the problem. I set the JRE of the plugin as well the JRE
for the Eclipse application instance to 5.0, but the compliance level
was set to 6.0. So javac 6.0 compiled my plugin code, while the Eclipse
instance has been running with 5.0.

Thank you all for your hints.
It would be fancy if the error message told me the version conflicts
instead of "is not currently available".
