MultiPageEditor - working with many files, marking MPE as dirty throw exception [message #901717]

Hi all,
I've got MultiPageEditor in which i've got 5 pages. On first page
there is an editor which extends GraphicalEditor(geEx), on second there are
2(logicInputEditor, logicOutputEditor) GroovyEditor's org.codehaus.groovy.eclipse.editor.GroovyEditor).
geEx is working with one file(e.g. first.qwe) and
logicEditors are working with 2 other files(in.groovy, out.groovy). In
geEx there is a code:

@Override
        public void commandStackChanged(EventObject event) {
                firePropertyChange(IEditorPart.PROP_DIRTY);
                super.commandStackChanged(event);
        }

When I edit file first.qwe MultiPageEditor know that something has
been modified and marks it and allow to save file - everything is
fine.

I add listeners to GrooveEditors:

logicInputEditor.addPropertyListener(new IPropertyListener() {
                         @Override
                         public void propertyChanged(Object source, int propId) {
                                 if (propId == IEditorPart.PROP_DIRTY){
                                         firePropertyChange(IEditorPart.PROP_DIRTY);

                                 }
                         }
                 });

I can't override commandStackChanged function, because GrooveEditor doesn't implement CommandStackListener.

Each time I edit something in one of GroovyEditors, the MultiPageEditor is changing its state to dirty - that's what i wanted, but also exception is printed on console. So - it's working as i want, but throwing and catching exception each time user type someting in editor is propably very

The message is:

The question is - how i can fix this? How should i send 'message' to MultiPageEditor, that one of GroovyEditors is 'dirty'?

Sory for my english Smile

I don't think the exception is related to the editor being 'dirty' or
not, but something about the kind of project your file is in. You'll
want to ask the developers of the Groovy editor you've mentioned. It is
not part of the Web Tools Platform.

I've already asked Smile

Your answer gave me a hint - i've changed editor type from GroovyEditor to TextEditor and everything is fine without any exception. It seems that propably it's bug in GroovyEditor(or GroovyEditor handles editor state in different way).
Thanks for your answer - it's not solution for my problem, but now I am one step closer to it(at least I hope so Wink

)

By the way - where can i find example of using 2 or more editors working on different files and handling state dirty/not dirty in MultiPageEditor? Any example or even plugin source will be a great help for me.
