I discovered a bug with the Treevirtual whereby it does not reselect all the previous selections when refreshed (in multi-selection mode). This is already apparent in the DemoBrowser where 2 selections are made in the set-up, but upon setting the datamodel, only one selection is actually displayed.
The fix uses the batchMode of the selectionModel to add each of the selections before ultimately firing the changeSelection event once all selections are added. For single selection mode, the effect will be the same as before where the last of the selections would be selected.
This is a link to a Playground example of the above Demo Browser with my fix applied:
