Comment 2 Michel Graciano 2010-02-24 09:43:01 UTC 
It happens if we use EditorRegistry.focusedComponent()/Registry.getMostActiveDocument() instead EditorRegistry.lastFocusedComponent(). Looks like this is an regression of issue #179368. BTW, the CopyFQN module was already fixed.
To reproduce it, just change the o.n.m.copyfqn.actions.CopyFQNAction:126 and follow these step:
1-Run the changed plugin;
2-Open any java class file;
3-Select any element, an class for example;
4-Go to Edit > Copy FQN and the exception is thrown.

If you use the shortcut instead (Ctrl+J Ctrl+C) everything works fine, what I understand is that the editor hos no longer the focus when the action is invoked by menu item.

In this particular case using ER.lastFC() is the right thing to do. I'll look at the changes done for issue #179368 and see if other places need fixing too. But in general R.getMAD() may have returned null and so any code calling it should have been prepared to handle nulls.

So, this is no longer a problem for CopyFQN, right? No one else has complained yet, so I guess the regression is not that bad. Nevertheless I'm going to doublecheck what the changes.

Yes, CopyFQN is already fixed and is no longer a problem. My compain is just about any regression in another places. Thanks for your help.
