In the Payload Renderer the java.lang.Character is listed incorrectly as STRING (this is the default in a switch statement in MapMessagePayloadPanel)
On uploading the XML message this propery is lost.

I will attach a patch for this based on the trunk which I think will work (unfortunately due to dependencies i was not able to build and test it).

p.s. thanks for a great tool
