> My resource defines an attribute which is a LIST of OBJECT that corresponds to a class (class name + module) and Properties that are passed to the created instance:
> {noformat}
>     private static final String CLASS = "class";
>     private static final String MODULE = "module";
>     public static final PropertiesAttributeDefinition PROPERTIES = new PropertiesAttributeDefinition.Builder("properties", true)
>             .setAllowExpression(true)
>             .build();
>     public static final ObjectTypeAttributeDefinition PROCESS_STATE_LISTENER = ObjectTypeAttributeDefinition.Builder.of("process-state-listener",
>             SimpleAttributeDefinitionBuilder.create(CLASS, ModelType.STRING, false)
>                     .setAllowExpression(false)
>                     .build(),
>             SimpleAttributeDefinitionBuilder.create(MODULE, ModelType.STRING, false)
>                     .setAllowExpression(false)
>                     .build(),
>             PROPERTIES)
>             .setRestartAllServices()
>             .setAllowNull(true)
>             .build();
>     public static final AttributeDefinition PROCESS_STATE_LISTENERS = ObjectListAttributeDefinition.Builder.of("listeners", PROCESS_STATE_LISTENER)
>             .setAllowNull(false)
>             .setRuntimeServiceNotRequired()
>             .build();
> {noformat}
> I can create the resource from the CLI:
> {noformat}
>  /subsystem=core-management/service=process-state-listeners:add(listeners=[{class=org.foo.Listener, module=org.foo,, properties = {foo  = true, bar  = ${bar.prop:2}}}])
> {"outcome" => "success"}
> {noformat}
> And the resource and its attribute is properly marshalled to the XML configuration:
> {noformat}
>             <process-state-listeners>
>                 <listeners>
>                     <process-state-listener class="org.foo.Listener" module="org.foo">
>                         <properties>
>                             <property name="foo" value="true"/>
>                             <property name="bar" value="${bar.prop:2}"/>
>                         </properties>
>                     </process-state-listener>
>                 </listeners>
>             </process-state-listeners>
> {noformat}
> However the resource can not be parsed and it fails with the exception:
> {noformat}

> The code in org.jboss.as.controller.AttributeParser#parseElement:197 to parse a list of objects assumes that the object's value are all represented by XML attributes. In my case, that's not correct as the "properties" attribute is represented by XML elements.
