Subject [jira] Created: (AXIS-2417) Deserialization fails if your schema defines arrays within arrays.
Date Wed, 22 Feb 2006 13:28:37 GMT
Deserialization fails if your schema defines arrays within arrays.

         Key: AXIS-2417
     Project: Apache Axis
        Type: Bug
  Components: Serialization/Deserialization  
    Versions: 1.3    
 Environment: Windows XP / Java 1.5
    Reporter: Martin Genhart
    Priority: Blocker

See the element PSWorkflow of the attached schema as an example. If you define subcomponents
as arrays and these subcomponents specify an attribute named "id", array deserialization may
fail because the deserialization context registers fixups based on the ids (prependend by
#). If like in the supplied example multiple arrays and array comonents define an "id" and
the id of different components is the same, deserialization may fail because the fixups are
only mapped by the "#id".

The fixups should instead be mapped by a fully qualified name. In the fix that I supplied
I use the ArrayClass from the registered deserializer as qualifier. See org.apache.axis.encoding.DeserializationContext.registerFixup(String,

    public void registerFixup(String href, Deserializer dser)
        if (fixups == null)
            fixups = new HashMap();

        +++ String qualifier = "";
        +++ Vector targets = dser.getValueTargets();
        +++ if (targets != null && !targets.isEmpty())
        +++ {
           +++ if (targets.get(0) instanceof DeserializerTarget)
           +++ {
              +++ DeserializerTarget target = (DeserializerTarget) targets.get(0);
              +++ if (target != null && instanceof ArrayDeserializer)
              +++ {
                 +++ ArrayDeserializer arrayDser = (ArrayDeserializer);
                 +++ ArrayDeserializer.ArrayListExtension listExtension = 
                    +++ (ArrayDeserializer.ArrayListExtension) arrayDser.getValue();
                 +++ if (listExtension != null)
                 +++ {
                    +++ Class destClass = listExtension.getDestClass();
                    +++ if (destClass != null)
                       +++ qualifier = "-" + destClass.getName();
                 +++ }
              +++ }
           +++ }
        +++ }
        +++ Deserializer prev = (Deserializer) fixups.put(href + qualifier, dser);

        // There could already be a deserializer in the fixup list
        // for this href.  If so, the easiest way to get all of the
        // targets updated is to move the previous deserializers
        // targets to dser.
        if (prev != null && prev != dser) {
            if (dser.getDefaultType() == null) {

While debugging this problem, I noticed that you do that same thing for attachement references.
I would assume that that code will have the same issue.

I noted that you use the attributes "id" and "href" for attachements and fixups. Does this
mean that attributes with these names are reserved for Axis? I have not found any documentation
regarding my question.
