Damitha Kumarage resolved AXIS2C-545.
-------------------------------------

    Resolution: Fixed
      Assignee: Damitha Kumarage

I just set a property AXIS2_HANDLER_ALREADY_VISITED after the incoming phases are passed from sandesha2c. So in mep_client I can check this property and avoid passing to the engine_receive again. Instead just return the response message context

> In RM 1.0 two way single channel scenario when it come to mep_client's engine_two_way_send function's engine_receive call the sandesha2_global_in_handler is already visited. So when engine_receive is called sandesha2_global_in_handler will be called twice. RM 1. 0 two way single channel implementation is a hack in sandesha2c to allow to do two way messaging in a single channel in RM. As a result this kind of unexpected difficulties arise. As a solution I can set a property  SANDESHA2_HANDLER_ALREADY_VISITED in axis2_msg_ctx  when the global in handler is visited once. So I can check this property from global_in_handler when it is visted again in the same response channel. To do that I need to do a small change
> in mep_client.c The changes is that I need to get the property map from msg_ctx and set it in response.
> If anybody see a better solution please let me know.
