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

Hello, is your problem similar to 
http://issues.apache.org/jira/browse/COCOON-1718?

> double-listbox problem in repeaters
> -----------------------------------
>
>          Key: COCOON-1738
>          URL: http://issues.apache.org/jira/browse/COCOON-1738
>      Project: Cocoon
>         Type: Bug
>   Components: Blocks: Ajax, Blocks: Forms
>     Versions: 2.1.8, 2.1.9-dev (current SVN)
>     Reporter: Fabrizio Sitzia
>  Attachments: cocoon-ajax.js.diff, forms-advanced-field-styling.xsl.diff, 
> forms-lib.js.diff
>
> Rendering a multivaluefield using the 'double-listbox' styling fails, when 
> that multivaluefield is contained in a repeater, and Ajax is enabled for the 
> form:
> The 'double-listbox'-styled fields in the repeater stop working as soon as 
> some action, involving a round-trip to the server and a partial re-rendering 
> of the repeater, is being performed (for example adding or deleting a 
> repeater row, validation error on submit...)
> After such a round-trip, a click on any of the double-listbox's UI elements 
> (double-click on an item, click on an option-transfer button) will yield a 
> Javascript error ("optxxxxx is not defined" on Cocoon 2.1.8, and 
> "from.options has no properties" on the current BRANCH_2_1_X)
> The multivaluefield's values will not be submitted correctly afterwards.
