YES! found it, I needed the #.FIELD_ATTR instead, so now I have
#.TYPE_ATTR
operationCode TYPE = FT_INT32 DISPLAY = BASE_DEC STRINGS =
VALS(myOperationNames)
errorCode TYPE = FT_INT32 DISPLAY = BASE_DEC STRINGS = VALS(errorCodeNames)
#.END
#.FIELD_ATTR
AssistRequestInstructionsArg/correlationID TYPE = FT_STRING DISPLAY = BASE_NONE
ScriptRunArg/uIScriptSpecificInformation TYPE = FT_STRING DISPLAY = BASE_NONE
ScriptEventArg/uIScriptResult TYPE = FT_STRING DISPLAY = BASE_NONE
#.END
Many thanks for you help.
