[Users] Dynamic Node does not bind to layer

[IT Intern]

Dear Matt,

Thanks for your feedback!  Unfortunately I have tried that and I still have
a little problem :-/.  When I remove the additional listener everything
works great, except every layer container on my tree now has a node for this
layer which is not what I want :(.  I need a way that I append a single node
to a single layer container ...

Thank you,

elshae
