Troubleshooting

I have a lot of NPE in some GUI-related methods for the Plugins

You might have errors such as:

      
         Unable to register my.plugins.MyPlugin plugin
         (java.lang.NullPointerException) 

Or:

      
         Unable to initialize after GUI creation in Plugin MyPlugin
         (java.lang.NullPointerException)   

Or:

      
         Unable to reset settings in Plugin MyPlugin
         (java.lang.NullPointerException)   

It might be that you defined the MenuFactory after you register the plugins. For example this code is incorrect:

  registerPlugins(); 
  mfactory = new MenuFactory(splashdialog);           

You should rather do:

   mfactory = new MenuFactory(splashdialog);
   registerPlugins();
