I think that your question is related to Eclipse more than ATL.
ATL editor inherits from the basic Eclipse's TextEditor, so you may have
to look how to launch that kind of editors programmatically.
Then you will be able to launch AtlEditor
(org.eclipse.m2m.atl.adt.ui.editor.AtlEditor class) as any other TextEditor.

Actually, I want to open the ATL editor in a RCP application. I've added
the ATL plugins to my project but when I try to open the ATL editor I get
this error message:

org.eclipse.core.runtime.CoreException: Text editor does not have a
document provider (...)

Well, to open a text editor I use a class called OpenAction that calls the
text editor itself. So to open the class that you mentioned "AtlEditor" I
would have to have a class like the "OpenAction" one, right? So if it's
right, which class is that?

Thank you,

best regards!
