----------------------------------

    Reporter: Marc Portier  (was: Marc Portier)

> [woody] initial binding framework
> ---------------------------------
>
>          Key: COCOON-761
>          URL: http://issues.apache.org/jira/browse/COCOON-761
>      Project: Cocoon
>         Type: Improvement
>   Components: - Components: Avalon
>     Versions: 2.1.8-dev (Current SVN)
>  Environment: Operating System: other
> Platform: Other
>     Reporter: Marc Portier
>     Assignee: Cocoon Developers Team
>     Priority: Minor
>  Attachments: woody-bind.patch, woody-bind.patch
>
> A first functional throw at the implementation of some Binding ideas for
> connecting Woody forms to actual back-ends.
> The enhancement is packaged as a patch for the Woody-block where it introduces
> - code in the o.a.c.woody.binding package
> - some new BindingManager component to be declared
> - supporting logging xpatch files
> - a sample showing the current features.
> - usage of a new xml-namespace: http://apache.org/cocoon/woody/binding/1.0 for
> the declarations in the 'binding'-file
> More explanation/ideas to be found on the mailarchives.

> Please direct your comments to the list.
> Known Limitations:
> - no documentation yet: should get into the wiki with the other woody-docos
> - no namespace-awareness concerning the xml-backend-objectmodel (how to express
> in jxpath?)
> - the repeater requires a unique id --> this calls for a hidden widget inside
> Woody (actually leaving it out from the template should do as soon as Woody
> learns how to deal with widgets that are missing on the form)
> - simple way to address this from flowscript is missing
> - BindingManager should maintain a cache of the bindings it build (pattern to be
> copied from woody form-manager, or factored out/reused)
> - no dataconversions yet: binding strictly 'String'
> - no binding for booleanfield and multivaluefield
> - list of builders probably nicer in the xconf in long run
> - use of jxpath was to enable binding to javabeans (coming from O/R layer)
> current patch lacks the sample though.
