Hi Chris,

I have removed the last file revision from CVS and got back to the
previous revision, which still has the problem reported to you earlier:
1. Start FreeMind with some map opened
2. Click "File" -> "New" => new map is created in the second tab
3. Change back to the already opened map by clicking the first tab
4. "File" -> "Close"
=> Exception is thrown:
java.lang.NullPointerException

freemind.controller.MapModuleManager.changeToMapModule(MapModuleManager.java:216)

...
The problem arises from the fact that Method fireStateChanged is called
before the internal vector pages is changed(jdk 1.4.2_13) . So the
called listener method stateChanged becomes wrong selected Title by calling
String selectedTitle = mTabbedPane.getTitleAt(selectedIndex);
The returned title still exists in mTabbedPane, but have already been
removed from the map module manager which creates the above exception.
So we still need a solution.
What is your opinion: who of us should care about this peace of code? It
would be great if you could get it working. If you can not reproduce the
problem, how could I help you?
Cheers, Dimitry
