I have an issue with the tree not listening to the specification of its selection mode. I have three trees, and all of them should allow only single selection, that works for one tree, that has only root node and children, but it doesn't work for the ones that have children and grandchildren. Even though I specify the selection node to be SINGLE_SELECTION, and it seems to be the case when I debug it to check whether that's the mode it uses. However, a user is still able to select multiple nodes in the tree.
