Sriram Chavali commented on CXF-852:
------------------------------------
I have also ran into this issue. It happens when the # of nodes to be
marshalled is > 1. If it is 1, then there is no problem. Issue seems to be in
org.codehaus.jettison.mapped.MappedXMLStreamWriter
Is there a separate tracker for the Jettison project?

> Key: CXF-852
> URL: https://issues.apache.org/jira/browse/CXF-852
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0
> Environment: Windows XP, Java 1.5
> Reporter: Derek Shaw
>
> When outputing lists of elements to JSON with an interface such as:
> @Get
> @HttpResource(location =
> "/media/objects/{containerID}/{startIndex}/{endIndex}")
> public List<Media> getMediaObjectList( @WebParam(name = "containerID")
> int containerID,
>
> @WebParam(name = "startIndex") int startIndex,
>
> @WebParam(name = "endIndex") int endIndex)
>
> throws MediaFault;
> If the object within the array contains an XmlAttribute annotation on one of
> its properties an exception is thrown in Jettison when retrieving the json
> response. Note that the XML response works as expected. The problem seems to
> be located at writeAttribute() in MappedXMLStreamWriter. The code attempts to
> cast a JSONArray to a JSONObject. Looks like perhaps there needs to be an
> instance of check as there is in other locations. Or that it is prematurely
> attempting to output the attribute before pulling the underlying object out
> of the Array, though this is just a guess....
> The workaround for me is to change the @XmlAttribute on the contained object
> to an @XmlElement.
