[ http://issues.apache.org/jira/browse/AXIS2-1254?page=comments#action_12440884 ] Amila Chinthaka Suriarachchi commented on AXIS2-1254: -----------------------------------------------------
When creating my earlier patch I did not notice the tracker variable at the template. So although it works it has some redundant code. In the new patch I have used the tracker variable to make it simplified. In addition to fixing this bug I have handle the nillable case in the serialization logic too. It is bit ambiguous the real meaning of the tracker variable. As I understood it is used to keep whether we have to serialize the associated element or not. In other words if the tracker is not available (i.e. minOccurs is 1) or present and true, we have to serialize the variable. Otherwise ( i.e. tracker is present and false) we can ignore it, since min occurs is zero. When serializing, if the variable is not null, we can serialize it without having any problem. If not (i.e if variable is null), if element is set to nillable then we write the null attribute, else throw and exception since this is an invalid state. > ADB cannot handle null return value from service method > ------------------------------------------------------- > > Key: AXIS2-1254 > URL: http://issues.apache.org/jira/browse/AXIS2-1254 > Project: Apache Axis 2.0 (Axis2) > Issue Type: Bug > Components: databinding > Affects Versions: nightly > Environment: Linux, Java 1.5 > Reporter: Dennis Sosnoski > Assigned To: Eran Chinthaka > Priority: Blocker > Attachments: ADBBeanTemplate.xsl-patch-041006.txt, > ADBBeanTemplate.xsl-patch-041006.txt, ADBBeanTemplate.xsl-patch-091006.txt, > bug.zip > > > When the response content is an optional element null should be a valid > return value from the corresponding method.
