Subject [jira] Commented: (SCXML-88) SCXMLSerializer does not serialize custom namespace declarations
Date Tue, 11 Nov 2008 16:04:44 GMT

    [ https://issues.apache.org/jira/browse/SCXML-88?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12646579#action_12646579

Rahul Akolkar commented on SCXML-88:
------------------------------------

Could be quite significant actually. Maps have high overhead, especially when they are close
to empty which these guys are (a map would perhaps be a logical choice, and thats what the
digester gives us so its also least effort). I'm leaning towards making some recommendations
if folks want to use the serializer. I won't be able to look at this immediately, but if you
(or anyone else) is able to whip up a patch, it can always be sooner. Thanks,

> The SCXMLSerializer writes the scxml namespace as the default namespace to the <scxml>
root tag and adds a "cs" ("commons-scxml") namespace by default.
> But it does not take into account that the original scxml document might contain other
namespace declarations, e.g. on child tags:
> <?xml version="1.0" encoding="UTF-8"?>
> <scxml xmlns="http://www.w3.org/2005/07/scxml" xmlns:cs="http://commons.apache.org/scxml"
version="1.0" initial="S1">
>  <state id="S1">
>   <!-- some E4X like condition using XML namespaces -->
>   <!-- redefine default namespace to "foo" and use explicit namespace prefix for scxml:transition
tag -->
>   <scxml:transition event="foo" cond="a.b.bar::c.* == 3" target="S2" xmlns="foo" xmlns:scxml="http://www.w3.org/2005/07/scxml"
xmlns:bar="bar">
>   </transition>
>  </state>
>  <state id="S2" final="true">
>  </state>
> </scxml>
> The above SCXML document is parsed properly and namespaces are forwarded to the executor
(i.e. it works correct).  But if it comes to serialization the namespaces are not serialized
properly.
