Changeset 1006 for XIOS/trunk/src/filter/input_pin.cpp

Message:

The workflow is now triggered when using xios_recv_field for fields in read mode received from the servers.

Previously the workflow was triggered upon receiving the data which could cause deadlocks since there are no garanties that clients are receiving data at the same time.
