Hi Rockdale, This is a nice easy one.
HL7 does allow extra components after the normal number allowed by the data type (in this case a single field as allowed by the ST data type). To access these, just call: ST string = ...... String component2 = string.getExtraComponents().getComponent(0); String component3 = string.getExtraComponents().getComponent(1); etc..
