-----------------------------------
Summary: ExtractHL7Attributes should better tolerate custom
segments (e.g. Z segments)
Key: NIFI-6320
URL: https://issues.apache.org/jira/browse/NIFI-6320
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.9.2
Environment: OSX iMac
Reporter: Gary Teichrow
Fix For: 1.10.0
If a user is processing an HL7 message that contains custom segments (e.g. Z
segments), an NPE is thrown at line 288 in ExtractHL7Attributes.java upon
encountering that segment. The call to segment.getNames() will return a list of
Nulls from HAPI for this custom segment.
Added a check whereby, if the user is using the "Use Segment Names" option in
the ExtractHL7Attributes processor and the HL7 message being processed contains
custom user segments (e.g., Z Segments), the code will downgrade to returning
the Segment Label as it does when this option is not used. Without this a null
pointer is thrown at line 288.
