Schema validation fails for NonNilable ResourceProperties, when child elements
of the resource properties are optional (minOccours="0")
---------------------------------------------------------------------------------------------------------------------------------------
Key: MUSE-159
URL: http://issues.apache.org/jira/browse/MUSE-159
Project: Muse
Issue Type: Bug
Components: WSRF WSRP ResourcePropertyCollection and Capabilities
Affects Versions: 2.0.0, 2.0.0 M2, 2.0.0 M1, 2.1.0
Reporter: Oliver Waeldrich
Assigned To: Dan Jemiolo
Priority: Minor
I have the following declaration for ResourceProperties in my wsdl-file:
<xs:complexType name="MyPropertiesType">
<xs:sequence>
<xs:element ref="tns:MyType" />
</xs:sequence>
</xs:complexType>
<xs:element name="MyType" type="tns:MyType1" />
<xs:complexType name="MyType1">
<xs:sequence>
<xs:element ref="tns:MyType2" minOccurs="0" />
</xs:sequence>
</xs:complexType>
However, the schema validation (validateSchema() in
SimpleResourcePropertyCollection) does not honor that the property may be empty
(e.g. <MyType/>) and recognizes it as nil. Therefore the schema validation
process breaks.
// some sort of "can be empty check" is missing here
if (!isNillable)
{
for (int n = 0; n < instances.length; ++n)
{
//
// check for child elements, attributes, and text, all of
// which qualify an element as "not null"
//
if (!instances[n].hasChildNodes() &&
!instances[n].hasAttributes() &&
XmlUtils.extractText(instances[n]) == null)
throw new SchemaValidationFault(message);
}
}
