[jira] [Created] (CXF-6874) NPE During Code Generation By Maven
Plug-In If Name Collision
Scott Pedigo created CXF-6874:
---------------------------------
Summary: NPE During Code Generation By Maven Plug-In If Name Collision
Key: CXF-6874
URL: https://issues.apache.org/jira/browse/CXF-6874
Project: CXF
Issue Type: Bug
Components: Build system
Affects Versions: 3.1.6
Reporter: Scott Pedigo
NPE if, in an XSD for a web service, types for the input and the output have elements with the same name and base type, but not the same restrictions (e.g. string type, but with min and max length defined for the input element, whereas just plain string for the output element).
See the elements {{businessRelationshipId}}, {{title}}, and {{sourceSessionId}} for example, in the following:
