If you are using latest 3.3 builds then the easiest is to add
'org.eclipse.ui.editors' as required plug-in and base your editor off
AbstractDectoratedTextEditor. If you do this you get the desired
behavior for free.

Hey Daniel,

Thanks for the reply!Its actually behaving the other way.
I have kept org.eclipse.ui.editors in my plug in dependencies.I have a
editor say
"MYEDITOR" which extends rcp based TextEditor.I also have a file
associated to myeditor.Now i open it in myeditor ,it is getting associated
correctly.Now i open it in text editor and update it ,when i go back to
myeditor ,no notification pops up where as when i update my file in
myeditor and switch back to text editor it pops up saying it has been
changed ..!
What do i need to do for the other way to happen?

Br,
bryan

If you edit the exact same file (even if external) then there should be
no notification.

The exact class is org.eclipse.ui.editors.text.TextEditor.
When there is a notification getting generated when u edit the file in the
associated editor and then switch to notepad ,why do u think there should
be no notification ,when iam trying to do the other way round?

Thanks in advance
Bryan

I didn't say that. I said, if you edit the same file with two different
ECLIPSE editors then they should share the same document and hence if
you type in one editor the change should automatically be reflected in
the other Eclipse editor.
