Hi,

I'm adding nodes to my JTree, but it is not being updated. If I add a node to the root, then the tree updates OK, but then if I add another, nothing happens. If I then add a node to the child of the node, then the tree updates OK and will show the node number as if all the other nodes have been added.

Anyway, here's the code

Thanks

Richard
