Trouble launching TextEditor from GEF [message #171233]

Hi,

I have a figure and it can be programmed using a simple low level language.
What I am trying to do is launch a TextEditor when I double click on the
figure.
In the performRequest method of the relevant EditPart when I receive a
REQ_OPEN I try to open a textEditor.
I use the following code to launch the Editor :

IEditorPart part = PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getActivePage().openEditor(input, "main.FBTextEditor");

FBTextEditor is a subclass of TextEditor.
The first problem I got was that I had no document provider. I overrode the
getDocumentProvider() method to return a new FilDocumentProvider.
Next I had to figure out what IEditorInput to pass.
I tried to pass a FileEditorInput with an IFile created as follows :

IFile newFile = ResourcesPlugin.getWorkspace().getRoot().getFile(path);

I tried passing both the path a file that doesn't exist and one that does.
When the Editor launched all that appeared was a blank editor space
containing the word "ERROR".
Any ideas guys cause this is wrecking my head.

Thanks,
Alan.

What was in the error log?

BTW, you'll probably get a better answer on the platform newsgroup.
