Hi All, now I'm working on the eclipse plug-in. Now I working of the editor extended from org.eclipse.ui.editors.text.TextEditor

And there is following code of marking the editor of dirty when something is changed

public class MyEditor extends TextEditor {
	public boolean isDirty() {		
		return mIsDirty;
        @Override public void createPartControl(Composite pParent) {
        mDocumentUndoManager = DocumentUndoManagerRegistry.getDocumentUndoManager(getSourceViewer().getDocument());
		OperationHistoryFactory.getOperationHistory().addOperationHistoryListener(e -> {
			if (e.getOperation().hasContext(mDocumentUndoManager.getUndoContext())) {
				// if there is no more operation to undo
				if (!OperationHistoryFactory.getOperationHistory().canUndo(mDocumentUndoManager.getUndoContext())) {
					mIsDirty = false;
				} else {
					mIsDirty = true;


Listener and isDirty method are called when I make the changes of text in the editor, but my Editor not marked as dirty, also I can't undo the changes.

May I ask to give me some ideas, where can be problem?
