Re: [Tm4j-tmnav-dev] tmnav extended to applet

Hi Rinalldo

I'm pretty sure that the reason for this is the potential asynchronious
behavior of the Preferences implementation.

I guess you are still running TMNav-Applet with the -f option? And
removed the call to System.exit(int);

If so, please try to add a call to sync in TMNav.clearSessionData():
After that the try - block should look roughly like this:
            try {
                String path = tmnavRootNode.absolutePath();
                tmnavRootNode.removeNode();
                tmnavRootNode.sync(); // new call to sync
                System.out.println("Removed Session Data from path " +
		...

If this does not help, try to add the sync call also to
TMNav.closeInstance(int), just after the line:
  session.storeSession();

(For the latter case you need to access tmnavRootNode just as in
clearSessionData().)

Hope that helps
