Comment 2 David Konecny 2013-05-14 22:23:27 UTC 
This Code Insert is meant to be triggered only on method declaration or more specifically only on class method name. And the method must be a REST producer method. If those conditions are met then the code insert converts the method into asynchronous one.

The fix is simple and save. I also changed the code so that Code Insert now does show up only on method names and nowhere else. If selected method is not REST producer method then error is shown in status bar saying "Only REST method is subject to convert".

While testing it I discovered a problem which I filed as issue 229754.

Comment 3 David Konecny 2013-05-14 22:33:49 UTC 
Btw. I just noticed that there are two ways to turn method into async one: via Insert Code and also via hint in editor gutter. I wonder if we need both.
