[jira] Commented: (CXF-852) Array responses containing XmlAttribute
cause exception in jettison
[ https://issues.apache.org/jira/browse/CXF-852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12523735 ]
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.
