The javadoc in the JAVA source needs to be updated, and there should be a conceptual doc.
Punting this to v1.
Many of this issues have been addressed in BEEHIVE-710, however, there is still no conceptual doc. A sample of how to use a dynamic tree would probably be very helpful. I have several tree jsp/jpf examples, let me know if you would like one of them to use for a reference.
Daryl O. contributed these docs at trunk/docs/forrest/release/src/documentation/content/xdocs/netui/tagsTree.xml
