Dennis Sosnoski reassigned AXIS2-1254:
--------------------------------------
Assignee: Eran Chinthaka (was: Dennis Sosnoski)
Assigning this back to you, Eran, since you're best qualified to evaluate and
apply Amila's patch.
I think we're in agreement on how this should work, that either nillable='true'
or minOccurs='0' should allow a null value to be passed or returned.
> ADB cannot handle null return value from service method

> Key: AXIS2-1254

> Components: databinding
> Affects Versions: nightly
> Environment: Linux, Java 1.5
> Reporter: Dennis Sosnoski

> When the response content is an optional element null should be a valid
> return value from the corresponding method. I tried this with the following
> WSDL/schema fragment:
>
> <element name="getBookResponse">
> <complexType>
> <sequence>
> <element name="book" minOccurs="0" type="tns:BookInformation"/>
> </sequence>
> </complexType>
> </element>
> <wsdl:message name="getBookResponse">
> <wsdl:part element="wns:getBookResponse" name="parameters"/>
> </wsdl:message>
> The result was an error on the server side when the corresponding method
> returned null:
> [java] Exception in thread "main" org.apache.axis2.AxisFault:
> java.lang.RuntimeException: book cannot be null!!
> [java] at
> org.apache.axis2.description.OutInAxisOperationClient.execute(OutInAxisOperation.java:298)
> [java] at
> com.sosnoski.ws.library.adb.LibraryAdbStub.getBook(LibraryAdbStub.java:340)
> [java] at
> com.sosnoski.ws.library.adb.WebServiceClient.main(WebServiceClient.java:45)
> ...
> A null return value should be accepted in this case, resulting in an empty
> wrapper element (<getBookResponse/>, in this case).
