Hi all, I have a a tree in my page and when I dont have any data Tree component throws a NPE. Is this intentional or am I somehow implementing/using the component in a bad way?

However I am confused by this behaviour. Is my implementation of the Nodes what is wrong? I see that NPE is coming from Tree so I dont think this on my end? Should I create a jira for this? -- View this message in context: http://tapestry.1045711.n5.nabble.com/NPE-in-Tree-when-I-dont-have-any-data-tp5720289.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
