An item with the same key has already been added.

Can you shed any light on what would cause this issue? Typically, it will happen when I group or when I try to sort on a column.

I'm using the grid to display a set of search results, 10 columns in total. There will be duplicate values in some columns as some identifiers (customer / transaction IDs, etc) may appear multiple times. The grid is bound via MVVM to an ObservableCollection of objects via the DataContext. The columns are set up as attributes of those objects on first bind of the DataContext.

The data comes up fine on first load; then has issues when we sort or group.
