NB: 5.0 + Matisse Update Pack
OS: All

I'm using 5.0 + Matisse Update Pack, which was downloaded from UC Beta.
I have a question about refactoring with Automatic Internationalization feature.

1. Run IDE
2. Create a project
3. Create a form
4. Put some components onto the form
5. Enable Automatic Internationalization

Now keys and values are extracted to Bundle.properties, like

NewJPanel.jButton1.text=jButton1
NewJPanel.jButton2.text=jButton2
NewJPanel.jButton3.text=jButton3

Then, I want to rename "NewJPanal" to other.

6. Select "NewJPanel.java" and try Refactor to rename it

filename and variable could be renamed, however, the
keys of properties are still "NewJPanel.....".

Refactoring resource bundle has not been implemented yet?
What is the best way for refactoring with this Automatic
Internationalization feature? We need to give the reasonable
scenario to users, because users often use such refactoring
for GUI.
