rowUpdated event
Hi! rowUpdated event fires when the data in row hasn't been updated. I open
row editor, and then close it without any modifications, but rowUpdated
event is fired. Any solution how to listen row data changes? I need to
manage state of my button (save) if row data before editor open are
different from the data after editor is close. Only in this case!

Thank you!

You could probably extend the default editor and override beginEdit() to create a copy of the item. Then in endEdit() you could perform an equality check on the previous and current versions of the item to see if the data actually changed.
But that seems like overkill. Is there any reason you can't simply rely on the update event?

if the user presses Escape - the editor won't call update() it's true. But
when click outside of editor the editor will call update() this is code of
editor:
@Override
public boolean mouseDown(Container container, Mouse.Button button,
int x, int y) {
Display display = (Display)container;
Window window = (Window)display.getComponentAt(x, y);
boolean consumed;
if (window != TableViewRowEditor.this
&& (window == null || !isOwner(window))) {
endEdit(true);
consumed = (getEditEffect() != null);
} else {
consumed = false;
}
return consumed;
}

As I recall, the editor won't call update() on the list if the user presses Escape or otherwise cancels the edit. As a result, the update event won't be fired.

But then how can I know is data has been changed after editor close? Or the
row has the same data as before editor has been opened?

The change event shouldn't be fired unless *something* has changed. So you shouldn't need to compare them (in other words, no change event = no change).

But when I change item previous and current are equals = changed item. How
can I compare them?
Have I implemented write listener?

The item's properties may have changed even if the item itself did not. An updated event is still fired in this case.

I try to listen list item:
tableDataListener = new ListListener.Adapter() {
@Override
public void itemUpdated(List list, int index, Object
previousItem) {
tableViewRowChangeListeners.rowDataChanged(GridView.this,
previousItem, index);
System.out.println(previousItem);
}
};
But previous (not changed) item always equals current(changed) item. What is
wrong?

Thank you!

You should be able to listen to the model data directly (i.e. listen for List change events).
