> 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).
