Description

Steps to reproduce:
1. Create a tree
2. Create Data source for it with hierarchical structure (at least 2 levels)
3. Apply filter to the data source and make number of element displayed in the tree smaller
4. Set one of the remain element selected via Tree.selectedItem

Actual Results:
Application completely dying

Expected Results:
Desired element being selected and highlights in the Tree

Workaround (if any):
There is no workaround.

>> In current example to kill the application it is enough to just press one of the buttons.

Bug is in ListBase.setSelectionDataLoop() {}
the loop :
while (items.length && !collectionIterator.afterLast)

{.....}

never ending because collectionIterator.afterLast always false even if we reached end of the array.
