I have a NullPointerException when I sorting store of an EditableGrid:

After I populate the store, call:


store.sort("id", Style.SortDir.ASC);


I have the same error, if I don't sort but click on a header column for sorting the column.

I omitted something to do?

I have found the problem: I don't setted the ID to a ColumnConfig.
The ID will be returned into findColumnIndex as dataIndex.
