t:dataTable with dynamic newspaperColumns

[Yaron Spektor]

Hi,
I was wondering if anyone knows why the t:dataTable does not accept a
backing bean value for the newspaperColumns value-binding? 

Where this example works (4 columns):
<t:dataTable newspaperColumns="4" newspaperOrientation="horizontal"
value="#{bean.valueList}" var="index" >
            <h:column>
                 <h:outputText value="#{index}" />                      
        </h:column>
</t:dataTable>

But this does not:

<t:dataTable newspaperColumns="#{bean.numberOfColumns}"
newspaperOrientation="horizontal" value="#{bean.valueList}" var="index"
>
            <h:column>
                 <h:outputText value="#{index}" />                      
        </h:column>
</t:dataTable>

Any work around to that? I can not use the t:columns.

Thanks,
