How do I get the current tree-selected item from a treeView? - acumatica

Question

Problem #1
I have a Form with a split panel with a tree view on the left side and a grid on the right side.
The tree view is displaying itemClassCD. When I select an item in the tree, the current selection is always the same itemClassCd (the first entry), or null. The code view from the Tree is as follows "Tree.Current.ItemClassCD".
Form with Tree and Grid
Problem#2
The second issue is related to the display of the tree nodes.
They are showing a "+" sign and they will keep opening if I press the sign.
