Ralph Goers reopened COCOON-2108:
---------------------------------


This patch causes XMLFileModule and anything based on AbstractJXPathModule or JXPathMetaModule to fail as they no longer receive the value of the element. 

> xmodule:flow-attr Does not accept document objects

> Sending document objects from flowscript back to the pipeline using
> xmodule:flow-attr produces unexpected results. Also, the examples from
> the documentation do not work as described:
>     http://cocoon.apache.org/2.1/861.daisy.html
> The most common error reported is:
>     'The object type: class java.lang.String could not be serialized to XML"
> This issue was discussed recently on the cocoon-users mailing list.
> The thread was introduced by Kazo Csaba with the subject "Sending DOM from flowscript to pipeline."
>  (July 17, 2007)
> He has attempted to trace this behavior in the source code and believes that a
> possibly-inappropriate conversion to string occurs in some cases.
> Jason Johnston suggested moving the issue to JIRA.
> I've created a demonstration of this apparent bug and some related problems
> in this very brief example:
>     http://www.csparks.com/xmodulePuzzle.txt
> I hope someone can fix or explain the correct usage of xmodule:flow-attr.
> Thanks to all,
> -Hugh Sparks, hugh@csparks.com
