Hi Lali,
Can you try following code snippet for getEditingDomain() method ?
/**
* @generated NOT
*/
public TransactionalEditingDomain getEditingDomain() {
IDocument document = null;
if (getDocumentProvider() != null) {
document = getEditorInput() != null ? getDocumentProvider().getDocument(
getEditorInput()) : null;
} else {
document = getEditorInput() != null ? getDocumentProvider(getEditorInput())
.getDocument(getEditorInput()) : null;
}
if (document instanceof IDiagramDocument) {
return ((IDiagramDocument) document).getEditingDomain();
}
return super.getEditingDomain();
}
Thanks,
Viraj.
