Subject [jira] Commented: (AXIS-1525) xsd:group behavior is wrong
Date Tue, 31 May 2005 23:06:53 GMT

Steve Green commented on AXIS-1525:

I've been looking into what it would take to fix the codegen for the sample wsdl you uploaded.
 In short, it's not going to be pretty.  Propogating maxOccurs for a group ref is tough because
there aren't necessarily CollectionType symbolTable entries for the group members.  I believe
that I can make it work though.  In the end, however, I believe that your point about element
order will still hold.  

I'll continue to work on a fix for maxOccurs group refs, but for the long term, does anybody
want to weight in on a "group aware" Bean{De}Serializer (or any other solution)?

>      Project: Axis
>         Type: Bug
>   Components: Serialization/Deserialization
>     Versions: 1.2 Beta

> WSDL2Java generates separate types for groups, and objects that reference groups end
up with a children object.  The problem is that serialization of that object should not show
the group in XML.  The elements of the group should appear on the wire as if they were elements
of the referencing object.
> It seems that the problem might be fixable by changing the way in which WSDL2Java generates
classes with groups.  The bean writer could recurse in to groups and treat the elements as
elements of the object being written.  This might create problems when trying to properly
handle xsd attributes like minOccurs=0, etc.. that appear on the group reference.
> Another possible solution would be to add some info to the type description so that the
serialization could could recognize a group reference and do the right thing.  The same would
need to be true of the deserializer.  This fix involves a change to the code generator as
well as changes to the Axis engine.
> N O T E:  I am interested in supplying a fix for this problem.  Please comments on this
issue so that I chose the method that best fits the design goals of the Axis developers.
