Issue with tree model [message #1603613]

Hello. I have a NatTable build with a custom tree data that works with a list of tree elements. Assuming that one of the elements are contained in two or more different parents, whenever i collapse one of those parents, the element is hidden only for the first parent( as the common child is reffered by the same index in the list). Any suggestions on how to make this work? Thank you!

Having the same child instance in several parents won't work.

The only thing that might work would be to implement equals and hashCode of your children to take the parent into account.
