Richface Tree menu and Seam
Hey guys, forgive me if this is the stupidest question you read today but I am really very new to programming as a whole. Basically, I need to have a rich:tree in my view that loads dynamically from the database. I am using the seam generated entity and list classes. When I try to load the view on the server I this in my console. Remember I am very new at java, not just seam! Thanks very much (the hibernate is actually retrieving from the database hence the stdout)

Sorry again if the solution is ridiculously obvious but I have been trying for ages and have looked everywhere, perhaps i just dont understand how to correctly implement a rich tree component?? Thanks for your help guys! I appreciate any! Everywhere i have read said that the tree could just read any Datamodel, and I assumed since the seam-gen program could use that information in a datatable, why can't i use it in a tree? Thanks.
