I've got an advanced datagrid that takes its source from an
array collection that has been filtered and then grouped.
When the user edits a certain item (called it adder), the
original item is cloned and reinserted (so the adder can stay in
the list). The edited item is then demoted to a non-adder item.
The adding seems to be painless enough, however, once the
item is added to the list, the only one that can be selected is the
cloned item. The original edited item cannot be selected. Where am
I going wrong here?
