Commented Issue: CheckListBox SelectedItems not behaving correctly when having a pool of items [18709]

Please see the example, I think everything should be clear then: Select a bookshelf and add a book. EDIT: I found a workaround, see my second ZIP, maybe it helps finding the issue.

Hi,
Can you send a complete sample ? I think the Converters are the differences here.

Thanks.
