Grid returns to default values when sorting

I am using XML for my data, which you can edit the grid. But when I edit and then sort the data, the default values come back. It's like when I edit a field on my table, it doesn't save it to the xml file.

Is there a way to save the grid back into the XML file? ie. from a 'save' button.

Matt,

look at the example here:

The trick is to call this.setItemText() after each modification and implement table.setText() on your data model.
