I attempted your solution Sebastien and did parameters.set("id", 43); This was one of the id's that was showing up in the link when I looked at the status bar. I still got the same error (string value exception) and it also said something about a null pointer. I'm at work and don't have the stack trace, but I thought it might be helpful to provide more info.
Any other thoughts on this?
