JS Error after loading the 3th node: Uncaught TypeError: settings is undefined

[strtob]

Hi,

after successful loading of a node, I get this error:

Uncaught TypeError: settings is undefined
    beforeSend jQuery
    beforeSend http://localhost:8080/assets/7b442736/js/kv-tree.js:775

The strange thing is that the first 2 node selections work like a charme, then this message occurs.

Any ideas would be appreciated!

Thanks a lot,
Tobi
