nullException [message #36866] Fri, 30 January 2004 12:47 Go to next message

I'm getting a nullException exception when loading a particular schema
file.
After investigating, it appears that it crashes on restricted enumerations
based on xs:positiveInteger. See xsd code below.

--mike

<xs:attribute name="layer">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="1"/>
<xs:enumeration value="2"/>
<xs:enumeration value="3"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>

<xs:element name="root">
<xs:complexType>
<xs:attribute ref="layer"/>
</xs:complexType>
</xs:element>

Mike,

Your example doesn't use positiveInteger and even if I change it and build a
complete schema like this:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:attribute name="layer">
<xs:simpleType>
<xs:restriction base="xs:positiveInteger">
<xs:enumeration value="1"/>
<xs:enumeration value="2"/>
<xs:enumeration value="3"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>

<xs:element name="root">
<xs:complexType>
<xs:attribute ref="layer"/>
</xs:complexType>
</xs:element>
</xs:schema>

I can't reprodue a null pointer exception.
