Hi,

I have a tableviewer with databinding like this:

ObservableListContentProvider cp = new ObservableListContentProvider();

for (TableViewerColumnDefinition definition : contentDefinitions) {

	IObservableMap attributeMap = EMFEditProperties.value(editingDomain, definition.getPropertyPath())
	.observeDetail(cp.getKnownElements());

	final TableViewerColumn viewerColumn = new TableViewerColumn(viewer, SWT.NONE);
	viewerColumn.getColumn().setText(StringL18n.getString(definition.getLabelKey()) + definition.getPostTitleText());
	viewerColumn.getColumn().setResizable(true);
	viewerColumn.getColumn().setMoveable(true);
	viewerColumn.getColumn().setWidth(definition.getWidth());

	viewerColumn.setLabelProvider(new GenericMapCellLabelProvider(getMessageFormat(definition) + definition.getPostCellText(),
					attributeMap));
}

viewer.setContentProvider(cp);
viewer.setInput(master);


When I add something to my resource, the UI is perfectly updated.. But the changes will not be recorded to the commandstack. How can I achieve this?

How do you add something to your resource? Using an AddCommand?

When I remove something I do it like this:

((EList<EObject>) (parentObject).eGet(property)).remove(obj);


Is it necessary to use commands? When modifying textfields etc, the framework takes care of everything...

Yes, you need to use commands for all changes.
