[jira] Updated: (MYFACES-189) Valuebinding in Converter and Validator attributes do not work for dynamic beans

["Manfred Geiler (JIRA)" <my...@incubator.apache.org>]

     [ http://issues.apache.org/jira/browse/MYFACES-189?page=history ]

Manfred Geiler updated MYFACES-189:
-----------------------------------

    type: New Feature  (was: Bug)

If you really want to add this feature, please do it in a derived x:convertNumber tag/converter so that it is clearly separated as an extension to specified standard behaviour.

>      Project: MyFaces
>         Type: New Feature

>     Reporter: Mathias Broekelmann

>
> It is not possible to use a value binding which references a dynamically created bean (like the row in a datatable) in the converter and validator tags. These valuebindings are evaluated at creation time (doStartTag() method in the tag).
> Here is an example which will not work:
> <h:datatable value="#{data.rows}" var="row">
>   <h:column>
>     <h:outputText value="#{row.numberValue}">
>       <f:convertNumber minFractionDigits="#{row.numberScale}"/> <-- this will not work since row is not found.
>     </h:outputText>
>   </h:column>
> </h:datatable>
> I'will provide the patches if there will be an agreement that this should work. Since it is not a problem to evaluate the bindings at the right time (when converting or validating the value).
