I have a custom perspective, which has it's own editor// it's not a TextEditorPart //. The problem I am experiencing is when i open my perspective, my editor is not opened. My question is how can i make it open my editor every time my perspective is opened? If anyone can help or has an idea :)
Thanks,
Peter

Where should I put this listener I mean should it be in the Activator class or another place, where?
Thanks,

I worked. I have a new problem now. The IEditorInput , i need an instance of it. I am suppling a treeViewer with information from an external engine that my app connects to. The information for the tree is provided by the ContentProvider i wrote for it. Why does the editor need an editor provider. I can't set the editorInput as null as the framework throws IllegalArgumentException. How can i go around that problem?

You can directly implement an instance of IEditorInput that your
specialized editor will know how to consume. Could just be a dummy one
if you don't need it, but that starts to beg the question of why it's an
editor and not a view...

It has to be an editor because I am parsing a specialized type of file (text most likely, but not only that so i cannot just extend the TextEditor class). I can create a dummy input just to test the editor itself. However i have a new problem now. I've put the :
PlatformUI.getWorkbench().getActiveWorkbenchWindow().addPage Listener(new IPageListener(){some code here}
Inside the Activator class ->start method. While in debug it tells me that first time i open the perspective the listener is added, and the pageActivated method is called, but the problem every subsequent attempt to open the perspective, respectively the editor doesn't result in the listen being invoked. Could it be because i have not registered the listener. (I don;t know how). Is it a good place to add the listener. Which is more appropriate?
