Hi,
So I think Emile has probably found the issue with this one... it's
not really that something is wrong, but since i wasn't seeing trace
info, I assumed there was. I'll try adding a child to the
selectedNode result and see what I get. I think I started by tracing
it and never got to the step where I was adding a child to the result.
I'll post results tonight.
Thanks for the help.
Brendan
