[jboss-dev-forums] [Design of JBossXB] - Mixing wildcards and elements

[kabir.khan@jboss.com]

Alex,

Can you please take a quick look at the XmlLoadableAopTestCase in the aop-mc-int project?

Basically we have

  | @JBossXmlSchema(namespace="urn:jboss:aop-beans:1.0", elementFormDefault=XmlNsForm.QUALIFIED)
  | @XmlRootElement(name="aspect")
  | public class AspectBeanMetaDataFactory extends AspectManagerAwareBeanMetaDataFactory
  |    implements BeanMetaDataFactory
  | {
  |    ...
  |    private List<Element> elements;
  |    
  | 
  |    public List<Element> getElements()
  |    {
  |       return elements;
  |    }
  | 
  |    @XmlAnyElement(lax=true)
  |    public void setElements(List<Element> elements)
  |    {
  |       this.elements = elements;
  |    }
  | 
  |    @Override
  |    public List<BeanMetaData> getBeans()
  |    {
  |       ArrayList<BeanMetaData> result = new ArrayList<BeanMetaData>();
  |       this.name = super.getBean();
  |    }  
  |     
  | }
  | 
  | @XmlRootElement(name="beanfactory")
  | @XmlType(name="beanfactoryType", propOrder={"aliases", "annotations", "classLoader", "constructor", "properties", "create", "start", "depends", "demands", "supplies", "installs", "uninstalls", "installCallbacks", "uninstallCallbacks"})
  | public class GenericBeanFactoryMetaData extends JBossObject implements BeanMetaDataFactory, Serializable
  | {
  |    ...
  |    protected Set<PropertyMetaData> properties;
  |  
  |    public Set<PropertyMetaData> getProperties()
  |    {
  |       return properties;
  |    }
  | 
  |    @XmlElement(name="property", type=AbstractPropertyMetaData.class)
  |    public void setProperties(Set<PropertyMetaData> properties)
  |    {
  |       this.properties = properties;
  |    }
  | 
  |    public List<BeanMetaData> getBeans()
  |    {
  |       ...
  |       if (properties != null && properties.size() > 0)
  |       {
  |          PropertyMap propertyMap = new PropertyMap(); 
  |          for (PropertyMetaData property : properties)   //CCE as explained below
  |          {
  |             propertyMap.put(property.getName(), property.getValue());
  |          }
  |          builder.addPropertyMetaData("properties", propertyMap);
  |       }
  |       ...
  |    }
  | }
  | 

In XmlLoadableAopTestCase.xml I have the following defined:

  |   <aspect class="org.jboss.test.microcontainer.beans.XmlLoadableAspect">
  |       <somexml>hello</somexml>
  |       <attribute name="IntAttr">12</attribute>
  |       <!-- <property name="property">Test1</property> -->
  |    </aspect>
  | 

"attribute" and "somexml" are wildcards, while "property" is declared on GBFMD. As it is the test is fine. If I remove somexml and attribute, and uncomment property it also parses fine. If I enable all three elements, I get a CCE at the point shown in GBFMD.getBEans(), since the properties map now contains one element of type org.apache.xerces.dom.ElementNSImpl instead of PropertyMetaData. I tried to reproduce this in the jbossxb project, but it worked as expected there, so I have probably missed some minor detail?
