Sorry, found the problem. I was returning an Array of String
(allocated, but not completely filled) with null elements
in String[] getChildrenNames
Still get the Node already exists Exception though ...

Hi there!
I run into the following exception. Afterwards I am unable to
connect (same error message all the time it seems).
Apart from that, I sometimes get "Tree-Node already exists" when
opening the connection.
