[ http://jira.codehaus.org/browse/XFIRE-839?page=comments#action_85157 ] Joost den Boer commented on XFIRE-839: --------------------------------------
As a last test, I changed the binding for ResultStringListUoCode.result to be of type Hashtable<String, List<Object>>. The WSDL and XML seem ok, on the client again a StackOverflowException occurs. The List just contains 2 objects. There are no circular references. Binding: <mappings xmlns:ail="http://www.aegon.com/ail/spil/Service";> <mapping name="ail:ResultStringListUoCode"> <!-- ignore succes property. Is determined by errorResult value. --> <property name="succes" ignore="true"/> <!-- global --> <property name="errorResult" class="java.util.Hashtable" keyType="java.lang.String" componentType="java.lang.String" /> <property name="result" class="java.util.Hashtable" keyType="java.lang.String" componentType="#codes" /> <component name="codes" class="java.util.List" componentType="java.lang.Object" /> </mapping> </mappings> WSDL: ... <xsd:complexType name="ResultStringListUoCode"> <xsd:sequence> <xsd:element minOccurs="0" name="errorResult" nillable="true" type="tns:string2stringMap"/> <xsd:element minOccurs="0" name="result" nillable="true" type="tns:string2ArrayOfAnyTypeMap"/> </xsd:sequence> </xsd:complexType> <xsd:complexType name="string2ArrayOfAnyTypeMap"> <xsd:sequence> <xsd:element maxOccurs="unbounded" minOccurs="0" name="entry"> <xsd:complexType> <xsd:sequence> <xsd:element maxOccurs="1" minOccurs="0" name="key" type="xsd:string"/> <xsd:element maxOccurs="1" minOccurs="0" name="value" type="xsd:ArrayOfAnyType"/> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> ...

A subclass property defined in a binding is not used for WSDL and XML -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe from this list please visit: http://xircles.codehaus.org/manage_email
