It seems like this might be a view matching problem between the java proxy interface and the server. A new text view had been added.
It also seems like it may be a data type problem (the proxy is expecting a particular data type but the server is sending back something different; again, could be mismatched views).
This particular message references type (P)
In the past I have also seen type (O), type (Z), and others. What is the significance of these types?
