Subject [jira] Commented: (COCOON-2108) xmodule:flow-attr Does not accept document objects
Date Tue, 14 Aug 2007 20:25:30 GMT

    [ https://issues.apache.org/jira/browse/COCOON-2108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12519763

Grzegorz Kossakowski commented on COCOON-2108:
----------------------------------------------

Hugh, I agree with all you said so far. I'm also glad to see that you tested your solution
thoroughly.

I think that the next step would be providing a patch. I'm especially interested in a patch
for trunk and I'll be happy to commit it as soon as you provide the patch.
Also, if there is some obscure use of getAttribute() method that relies on buggy functionality
we should fix it. Since it's hard to discover such hypothetical code we just must let new
code go into wild and see what happens.

> 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,
