choice of sequence of union causes infinite loop in generated ADB binding
-------------------------------------------------------------------------
Key: AXIS2-3401
URL: https://issues.apache.org/jira/browse/AXIS2-3401
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: adb, wsdl
Affects Versions: 1.3
Environment: Eclipse (Europa) with Axis2 Code generated by the Code
Generator Wizard
Reporter: Christoph Ludwig
We have a WSDL file that contains a schema similar to the following snippet:
<xsd:complexType name="dateType">
<xsd:choice>
<xsd:sequence>
<xsd:element name="notBefore"
type="tns:DateOrDateTime" minOccurs="1" maxOccurs="1">
</xsd:element>
<xsd:element name="notAfter"
type="tns:DateOrDateTime" minOccurs="0" maxOccurs="1">
</xsd:element>
</xsd:sequence>
<xsd:element name="notAfter"
type="tns:DateOrDateTime"
minOccurs="1" maxOccurs="1">
</xsd:element>
</xsd:choice>
</xsd:complexType>
<xsd:simpleType name="DateOrDateTime">
<xsd:union memberTypes="xsd:dateTime
xsd:date"></xsd:union>
</xsd:simpleType>
The intention is that an element of type DateType has two optional elements
notBefore and notAfter, but at least one of these elements has to be there.
However, the generated DateType.parse(javax.xml.stream.XMLStreamReader reader)
enters an infinite loop when both elements are provided. The problem is that it
correctly evaluates the type attribute in the notBefore element in
DateTypeSequence_type0.parse(javax.xml.stream.XMLStreamReader reader), but
fails to find the Java class this type is bound to.
The generated code exhibits another problem as well, I think: When parsing an
element of Type DateOrDateTime, it expects a type attribut. But if there is no
type attribute, then it should try the various union types in the order of
their declaration, cf. section 2.5.1.3 of
<URL:http://www.w3.org/TR/xmlschema-2/#atomic-vs-list>.
