Valuebinding in Converter and Validator attributes do not work for dynamic beans
--------------------------------------------------------------------------------
Key: MYFACES-189
URL: http://issues.apache.org/jira/browse/MYFACES-189
Project: MyFaces
Type: Bug
Versions: Nightly Build
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).
