Hello Keith, I believe the reason is: both of the two destination variables in the two copy activities has not been initialized. See the WS-BPEL standard 2.0(April 11,2007) at page 48 (Section 8.1): "A global variable is in an uninitialized state at the beginning of a process. A local variable is in an uninitialized state at the start of the scope it belongs to." and "An attempt during process execution to read a variable or, in the case of a message type variable, a part of a variable before it is initialized MUST result in the standard bpel:uninitializedVariable fault."
I guess other BPEL engines might implicitly intialize the destination variable of copy. To locate where in the process the fault takes place, the console output of ODE is a good choice, which by default contains some verbose DEBUG/ERROR information. Haven't you read them?
