Hi Henry, I also faced the same issue in my project. I got one solution to this.
In method clickedItem(), you are traversing through the XML. Instead you can take the selectedXML and traverse it through tree dataprovider i.e. XMLList and then use that to expand the child of that node of tree. This problem is because of different UID of tree. Hope this solve your issue.
