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
        at org.apache.xmlbeans.impl.schema.StscChecker.checkElementDefaults(StscChecker.java:206)
                
        at org.apache.xmlbeans.impl.schema.StscChecker.checkFields(StscChecker.java:152)

        at org.apache.xmlbeans.impl.tool.SchemaCompiler.compile(SchemaCompiler.java:1072)
                
        at org.apache.xmlbeans.impl.tool.SchemaCompiler.main(SchemaCompiler.java:368)
(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>
