-------------------------------------
Resolution: Invalid
No bug. Using the right syntax worked perfectly.
> Unmarshal using ref is not working when upgrading to camel 3.1

> Key: CAMEL-14656
> URL: https://issues.apache.org/jira/browse/CAMEL-14656
> Project: Camel
> Issue Type: Bug
> Components: camel-xstream
> Affects Versions: 3.1.0
> Environment: Camel 3.1.0
> Reporter: Mattias Andersson
> Priority: Critical
>
> Hi,
> In Camel we use route that looks like this:
>
> {code:java}
> <route
> ....
> <unmarshal ref="xstream-default" /> <-- This does not work anymore
> <dynamicRouter>
> <method method="route" ref="dynamicRouter" /> </dynamicRouter>
> <marshalref="xstream-default" />
> ....
> </route>{code}
>
>
> We registered the "xstream-default" in the camel context.
>
> {code:java}
> XStreamDataFormat xD = new XStreamDataFormat();
> xD.setPermissions("*");
> xD.setEncoding("UTF8");
> dataFormats.put("xstream-default", xD);
> {code}
> {code:java}
> camelContext.setDataFormats(dataFormats);
> {code}
> and loads the xml using:
>
> {code:java}
> try (InputStream is = EventRouteTree.toInputStream(doc)) {
> RoutesDefinition routes = (RoutesDefinition)
> camelContext.getXMLRoutesDefinitionLoader()
> .loadRoutesDefinition(camelContext, is);
> routes.getRoutes().forEach(r -> {
> camelContext.addRouteDefinition(r);
> });
> }
> {code}
>
>
> This worked fine i Camel 2.x but doesn't work in Camel 3.1 anymore. Tried to
> look at the upgrade 2.x to 3.0 guide but I found nothing specific regarding
> unmarshal.
> According to the xsd it look like there is no "ref" anymore for the unmarshal
> defintion .
> [https://camel.apache.org/schema/spring/camel-spring-3.1.0.xsd]
>
> I get the error when camel tries to start the route.
>
> {code:java}
> Caused by: java.lang.IllegalArgumentException: ref or type must be specified
> at org.apache.camel.util.ObjectHelper.notNull(ObjectHelper.java:152) at
> org.apache.camel.reifier.dataformat.DataFormatReifier.getDataFormat(DataFormatReifier.java:164)
> {code}
> Which looks strange because the ref is defined in xml tag unmarshal.
> So i guess since the xsd doesn't allow for a ref then the parser ignores the
> ref and it is empty when the code below is executed. Is this bug or are we
> suppose to define this in another way in the XML?
