Bug 327873

Description Stian Soiland-Reyes 2010-10-15 06:34:14 EDT

(Not sure why Eclipse selected ACTF/accservice as component - the component in question is the default XSD Editor in Eclipse for J2EE)


What steps will reproduce the problem?
1. In rdf.xsd, make an attribute 
	<xs:attribute name="parseType">
		<xs:simpleType>
			<xs:restriction base="xs:string">
				<xs:enumeration value="Collection"></xs:enumeration>
				<xs:enumeration value="Resource"></xs:enumeration>
			</xs:restriction>
		</xs:simpleType>
	</xs:attribute>

2. In workflowBundle.xsd - import rdf.xsd - and make a type using this type.
	<xs:complexType name="OutputPortBinding">
		<xs:sequence>
			<xs:element name="bindsOutputActivityPort" type="rdf:Resource" />
			<xs:element name="bindsOutputProcessorPort" type="rdf:Resource" />
		</xs:sequence>
		<xs:attribute ref="rdf:parseType" use="required" fixed="Resource" />
	</xs:complexType>

3. Any kind of editing in the 'Source' tab of workflowBundle.xsd within the <xs:attribute> will - character by character - bring up a dialogue complaining about "Argument cannot be null". - presumably because the XSD 'Design' bit of 'Properties' is struggling to update the list of restrictions or similar.

The files in question can be checked out from http://github.com/myGrid/scufl2/blob/eclipse-xsd-bug/scufl2-usecases/src/main/resources/workflows/example/workflowBundle.xsd
