Nullpointer Exception in String Tokenizer
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.

Re: Nullpointer Exception in String Tokenizer
Posted by Thomas Bopp <as...@uni-paderborn.de>.
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 ...
