[mule-user] does MULE EE 3.2.1 supports XMLToMapsTransformer?

[kakani yughandhar]

i am facing the following issue when using XMLToMaps transformer.

<xm:dom-to-xml-transformer name="DomToXml"/>
<jdbc:xml-to-maps-transformer name="xml2maps"/>

first transformer converting the payload to XML string and passing it to next transformer but it is failing with the following exception.any help or pointer on this issue is very much appreciated.

org.apache.cxf.interceptor.Fault: Could not find a transformer to transform "CollectionDataType{type=java.util.ArrayList, itemType=java.lang.Object, mimeType='text/xml'}" to "SimpleDataType{type=javax.xml.stream.XMLStreamReader, mimeType='*/*'}".

Not enough details without the flow config, but it looks like there's a list coming in. Have you considered using a splitter maybe in front?

Hi,

Check your namespace prefix. Those should be xml.

Also, from the stacktrace it seems the content of your payload is not an object. Is an ArrayList. So transformer are receiving an unexpected type.
