How do I add more than one property to a message?

[jbeerhalter]

Is there a way to add more than one property to a message with NMS?

For instance,

IBytesMessage.Properties.SetString(string,string) only seems to work the first time that I call it. Any subsequent seem to be ignored with no exceptions thrown.

I'd like to add multiple properties to a message, and looking at the source code, it seems like that was the intention, but I can't figure out how to do it.

Nevermind I found the problem, you can't have a property of key "Type". That doesn't generate exceptions, it just gets ignored.
