In the current transformation I am working on I thought I would try using the ADT_AXX superstructure, since multiple ADT types need to be handled. Some complexity was present, given that the inbound has several Z-Segments, which I have built definitions for, and the outbound has one of a different structure to the inbounds.
Snippets from the code dealing with them are shown below. The hl7In mentioned is of ADT_AXX type. ADT_AXX hl7Out = new ADT_AXX(); hl7Out.setValidationContext(new NoValidation()); ZPX zpxIn = new ZPX(hl7In.getParent(), hl7In.getModelClassFactory()); ZVX zvxIn = new ZVX(hl7In.getParent(), hl7In.getModelClassFactory()); GenericSegment zSeg; try { zSeg = (GenericSegment) hl7In.getINSURANCE().get("ZPX"); zpxIn.parse(zSeg.encode()); } catch (HL7Exception ex) { // Problem finding zpx leave it empty } try { zSeg = (GenericSegment) hl7In.getINSURANCE().get("ZVX"); zvxIn.parse(zSeg.encode()); } catch (HL7Exception ex) { // Problem finding zvx, leave it empty } hl7Out.addNonstandardSegment("ZPD"); GenericSegment zpdGen = (GenericSegment) hl7Out.get("ZPD"); ZpdEdis zpdOut = new ZpdEdis(hl7Out.getParent(), hl7Out.getModelClassFactory()); SegmentTranslation.processZpd(zpxIn, hl7In.getPV1(), zvxIn, zpdOut); zpdGen.parse(zpdOut.encode()); All of this works very nicely, and all was proceeding through test cases for different message types with me reviewing the content of a .printstructure(). I got a nasty surprise when I finally came to .encode() the result: java.lang.NullPointerException at java.util.Collections$UnmodifiableCollection.<init>(Collections.java:994) at java.util.Collections$UnmodifiableSet.<init>(Collections.java:1066) at java.util.Collections.unmodifiableSet(Collections.java:1056) at ca.uhn.hl7v2.model.AbstractSuperMessage.getStructuresWhichChildAppliesTo(AbstractSuperMessage.java:78) at ca.uhn.hl7v2.validation.builder.support.OnlyAllowableSegmentsInSuperstructureRule.checkStructure(OnlyAllowableSegmentsInSuperstructureRule.java:71) at ca.uhn.hl7v2.validation.builder.support.OnlyAllowableSegmentsInSuperstructureRule.apply(OnlyAllowableSegmentsInSuperstructureRule.java:55) at ca.uhn.hl7v2.validation.builder.support.OnlyAllowableSegmentsInSuperstructureRule.apply(OnlyAllowableSegmentsInSuperstructureRule.java:46) at ca.uhn.hl7v2.validation.AbstractValidator.testMessageRules(AbstractValidator.java:98) at ca.uhn.hl7v2.validation.AbstractValidator.validate(AbstractValidator.java:82) at ca.uhn.hl7v2.parser.Parser.assertMessageValidates(Parser.java:611) at ca.uhn.hl7v2.parser.Parser.encode(Parser.java:275) at ca.uhn.hl7v2.parser.PipeParser.encode(PipeParser.java:1003) at ca.uhn.hl7v2.model.AbstractMessage.encode(AbstractMessage.java:207) at au.gov.qld.health.sit.transform.hl7.HbcisNormAdtTxEdisTest.testTransformA01(HbcisNormAdtTxEdisTest.java:81) Doing a .setValidationContext(new NoVAlidation) on the result message does not prevent the error. Is there anything I can do to enable this result to .encode()? The prinstructure() shows everything exactly as I want it.
