NPE on complex elements with default or fixed values
----------------------------------------------------
Key: XMLBEANS-316
URL: https://issues.apache.org/jira/browse/XMLBEANS-316
Project: XMLBeans
Issue Type: Bug
Affects Versions: Version 2.1, Version 2.2, Version 2.2.1
Environment: Sun Java 6 (build 1.6.0-b105), Linux
Reporter: Benjamin Gufler
Compiling an XML schema which defines default or fixed values for elements with
complex types leads to a NPE in StscChecker:
Exception in thread "main" java.lang.NullPointerException

org.apache.xmlbeans.impl.schema.StscChecker.checkElementDefaults(StscChecker.java:206)

(The line numbers in this stack trace refer to xmlbeans-2.2.0, but the same
error arises with 2.1.0).
Here's a minimal subset of the schema I'd like to compile which reproduces the
error:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:element name="Segment" type="Spectrum" />
<xs:complexType name="Spectrum">
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1"
name="SegmentType" type="TextParam" default="Spectrum" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="TextParam" mixed="true">
<xs:attribute name="name" type="xs:string">
</xs:attribute>
<xs:attribute name="ucd" type="xs:string">
</xs:attribute>
</xs:complexType>
</xs:schema>
