Treeview: widget does not load

Treeview widget used for the firsttime. Configured it for a simple situation. It does not open and sais: Could not create widget TreeView.widget.TreeView: TypeError: De eigenschap of methode fixObjProps wordt niet ondersteund door dit object'. Anyone an idea where to start looking for the answer or experienced this before?

The Treeview-widget uses jQuery and since a newer version of the Treeviw-widget, the newest jQuery library doesn't come with the Treeview-widget anymore. What you could do is make sure the newest jQuery library is included. in your project, by adding a line to the head of your index.html:

<script src="//"></script>

Hope this helps!
