Re: [castor-dev] Subclass unmarshalling in castor

[asim razzaq]

I do have all FieldDescriptors compiled and in the path.
The marshalling framework generates the following:
<thirdObject>
   <obj xsi:type="subObject">
      <name>name</name>
   </obj>
</thirdObject>
It complains that "name" is not deifined in the FieldDescriptor for 
ParentObject.

I had thought that the xsi:type would cause Castor to unmarshall to 
subObject and not
parentObject. Is there some property in castorbuilder.properties that forces 
castor to do that?
In fact currently I am using the xsi:type to do my own unmarshalling for the 
XML to subObject, but it becomes tedious as I increase the scope of the 
project and I think castor should be able to handle subclass unmarshalling.

Thanks.

Can you show an example of the "marshalled" XML, Castor should be adding
an xsi:type attribute to the <obj> element that will allow Castor to
know it's a subObject and not a parentObject.
Such as:

<thirdObject>
   <obj xsi:type="subObject">
      ...
   </obj>
</thirdObject>
Also, have you compiled the generated descriptors?
