Insert new TreeNode how to make it show

[erikswed]

I´m adding 3 TreeNodes like

-N1 ----N2 ------N3

In the N2 node I´m creating a new node named N33 and doing Node.addChild(node); and I expected my tree to look like this but nothing happens! -N1 ----N2 ------N3 ------N33

How do I update invalidate the tree? I try androidTreeView.getView().invalidate(); but that gives "IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first."

@erikswed have you found any solution?

Yes in my case I just do androidTreeView.expandAll(); from within N2. In my case the N2 is responsible for adding the nod.
