rich:tree with recursiveTreeNodesAdaptor
hi,
i'm trying to implement a rich:tree with recursiveTreeNodesAdaptor and i've read through all of the examples and cant figure what's wrong.
Environment is Seam 2.0.2CR1, JBoss 4.2 and RichFaces 3.1.4 I have seen examples where there was no need for writing TreeModel/Node adaptor.
The control is for selecting a category from a simple adjacency list object tree (parent, children) to assign to a item.
The model is correct as i have testng tests and the seam components get initialized correctly, all the controls appear except the tree itself.
Do i miss anything?
