Wicket will not force any method or framework down your throat, wicket
is a web framework. It's completely up to yourself to decide which way
you want to go.. Its probably why you get so differentiated answers.
Whether you use spring or databinder or something else is up to you.

Hi Per,
did you try using a wicket.markup.html.basic.MultiLineLabel?
If your tree nodes have more than one component, encapsulate them into
a Panel and return instances of that from
BaseTree.newNodeComponent(String id, IModel model).
Cheers,

One thing you can check is if you have any references (instance variables,
