Subject [jira] [Created] (CAMEL-10817) dumpModelAsXml can return invalid XML namespace xmlns:xmlns
Date Fri, 10 Feb 2017 16:49:41 GMT

---------------------------------------

             Summary: dumpModelAsXml can return invalid XML namespace xmlns:xmlns
                 Key: CAMEL-10817
                 URL: https://issues.apache.org/jira/browse/CAMEL-10817
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.18.0
            Reporter: James Netherton
            Assignee: James Netherton


Seems I introduced a [bug|https://github.com/apache/camel/blob/master/camel-core/src/main/java/org/apache/camel/model/ModelHelper.java#L99]
when implementing CAMEL-10509.

If we're processing a namespace prefix of 'xmlns' then obviously we should not prefix it with
the same value. But currently this is allowed and a namespace prefix of 'xmlns:xmlns' is added
to the {{<routes>}} element. This can mean that the output from {{ModelHelper.dumpModelAsXml}}
is invalid.

However, I can only reproduce the problem on Karaf where the routes use xpath expressions.
Some how with other platforms & scenarios the 'xmlns:xmlns' value is being ignored and
never makes it into the {{dumpModelAsXml}} output.
