Vaadi 8.3 - Adding an Item to a Tree more than once

Vaadin 6 / 7 / 8 Framework UI

In Vaadin 7 I was able to add an item to a tree more than once.
In Vaadin 8 I get an error (Cannot add the same…).
How can I solve that issue ?
Any workaround ?

Hi,

you might need a wrapper object and provide separate instances for each similar object.
