Subject [jira] [Commented] (AXIOM-362) SOAPHeader examineAllHeaderBlocks throws ClassCastException
Date Mon, 11 Apr 2011 18:21:06 GMT

    [ https://issues.apache.org/jira/browse/AXIOM-362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13018477#comment-13018477
] 

Andreas Veithen commented on AXIOM-362:
---------------------------------------

Found an interesting comment in LLOM's SOAPHeaderImpl#addChild method:

        // Make sure a proper element is added.  The children of a SOAPHeader should be
        // SOAPHeaderBlock objects.
        // Due to legacy usages (AXIS2 has a lot of tests that violate this constraint)
        // I am only going to log an exception when debug is enabled. 

Action plan:
* Fix the Axis2 test cases that add plain OMElement instances to SOAPHeader.
* Change the addChild implementation to throw an exception if the child is not a SOAPHeaderBlock.

> The HeaderIterator does check for nodes other than a SOAPHeaderBlock node, except for
the first element. The method 'hasNext' does check if nodes are SOAPHeaderBlock nodes.
