Mathias Broekelmann updated MYFACES-189:
----------------------------------------

           type: Bug  (was: New Feature)
    Description: 
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).

    Environment: 

Changed to bug since I´ve not found in spec that it forbids use of 
valuebindings for validator and converter properties.
