Hello Martijn, We needed such an extension too at work. Based on org.apache.cocoon.forms.formmodel.tree.DefaultTreeModel, I was able to create a widget that reads its contents from an XML document. The current implementation is a little ugly but it works. The widget parses the XML document (using XOM) and then this document is transformed into the tree structure used in DefaultTreeModel. I'll send you the sources. One improvement we need is the possibility to access extra data in the XML document.
