Description Christoph Keimel CLA 2015-05-18 04:31:01 EDT 
FilterableTreeItem overrides TreeItem#isLeaf. This is a temporary workaround until RT-40790 [1] has been adressed and should be removed/refactored when the problem is solved.

Without this workaround TreeView does not recognize empty folders (after filtering) as leaves and will still display the expand/collapse controls next to the tree item. The reason behind this is that the leafProperty is hooked internaly to the source list and not to the filtered list.

Comment 1 Christoph Keimel CLA 2015-11-25 07:55:46 EST 
FilterableTreeItem no longer overrides isLeaf() but uses reflection to manipulate the private field "children" of TreeItem. This can be refactored if the JavaFX issue JDK-8091687 [1] gets resolved.
