How do I determine if a MD File is being closed whilst my extension is active? If you open a different file all of the object references in the extension become invalid.

   Hi Mike,

   Great question!

   You can cast the FeatureModuleContext to com.moneydance.apps.md.controller.Main and then call mainObj.addAppEventListener(new com.moneydance.apps.md.controller.AppEventListener() {
     public void handleEvent(String eventID) {
       if("md:file:closing".equals(eventID)) {
         // call some cleanup code here
       }
     }
   });

   Thanks,
   Sean

   Hi chaps,

   You can also override the handleEvent method in your Main class (I assume it extends FeatureModule) if that's an appropriate place for you to be notified.

   @Override
   public void handleEvent(String appEvent) {
   
       if ("md:file:opened".equals(appEvent)) {
           onAccountSetOpened();
       }
   
       if ("md:file:closing".equals(appEvent)) {
           onAccountSetClosing();
       }
   
   }
   

   Cheers,
   Kevin

   Ah yes, that is far better. Thanks Kevin!

   Thanks Kevin and Sean

   Kevin's answer made me look at FeatureModule in more detail and I saw the cleanUp() method. Would that do what I want, i.e. to know when to close my extension down?

   Interesting, I have just done a test and put a breakpoint on the cleanup method. It was not called when I changed files.

   Next test is Kevin's solution

   That worked and all windows were closed. I will add this to my Wiki concerning extension writing.

   Thanks for the help
