Subject [jira] Created: (COCOON-2108) xmodule:flow-attr Does not accept document objects
Date Thu, 09 Aug 2007 17:05:43 GMT
xmodule:flow-attr Does not accept document objects
--------------------------------------------------

                 Key: COCOON-2108
                 URL: https://issues.apache.org/jira/browse/COCOON-2108
             Project: Cocoon
          Issue Type: Bug
          Components: * Cocoon Core
    Affects Versions: 2.1.11-dev (Current SVN)
            Reporter: Hugh Spark
            Priority: Minor


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:

I hope someone can fix or explain the correct usage of xmodule:flow-attr.

Thanks to all,
