Eclipse plugin "Operation not enabled"

Question

I'm struggling with Java Refactoring - I need to write an Eclipse plug-in which will refactor some code. It's really difficult for me and it would be way easier if I could follow working code step - by - step. The only alike example I could find is a sample Introduce Indirection.

Unfortunately I cannot make it actually work. I get "chosen operation is not currently available" information anytime I try it.

I've imported code, "Run As -> Eclipse App" and than tried to use Introduce Ind. from Eclipse Articles. What am I doing wrong?

I'll be happy with any help :).

Check your handler class for isEnabled() method. I suppose when creating new handler the default value for this method returns false. That can be the issue.
