When the odatagen is used to generate classes for services that has complex type inside the FunctionImport section there is an issue in the class header - missing namespace prefix in the h and m files
in the class that inherited from the ObjectContext is generated like

• (ApplyDecisionOutput *) ApplyDecisionWithworkitem_id:(NSString *)workitem_id dec_key:(NSString *)dec_key comments:(NSString *)comments;
   
  would expected to:
• (WFODCPROCESSING_ApplyDecisionOutput *) ApplyDecisionWithworkitem_id:(NSString *)workitem_id dec_key:(NSString *)dec_key comments:(NSString *)comments;
