radio buttons in a table, "index" attribute of t:radio

[Sebastien David]

Hi,

I would like to build a datatable, containing one radio button per line. This subject is in every forums I found, but my problem is very strange. I use Tomahawk components. Here is a part of my code:

<to:selectOneRadio
id="selectedList" 
forceId="true"
forceIdIndex="false"
layout="spread" 
value="#{bean.selectedList}" >
<f:selectItems value="#{bean.listesSI}" />
</to:selectOneRadio>
 
<to:dataTable
headerClass="tableHeader"
columnClasses="libelleCol,checkCol"
value="#{bean.listes}"
var="lst"
rowIndexVar="index">
<h:column>
<f:facet name="header">
<h:outputText value="" />
</f:facet>
<h:outputText value="#{lst.libelle}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="" />
</f:facet>
<to:radio for=":myForm:selectedList" index="#{index}" ></to:radio>
</h:column>
</to:dataTable>

I've got a NullPointerException error when the "index" attribute of the radio component is filled with a dynamic value. If I replace index="#{index}" by index="0", it works fine but every radio button will have the same value. And If I display the #{index} via a h:outputText, the line index is correctly displayed.

Here are the first lines of the stack trace:

java.lang.NullPointerException
at com.sun.facelets.tag.TagAttribute.getInt(TagAttribute.java:100)
at com.skalasoft.facelets.tags.IntegerMetadata.applyMetadata(IntegerMetadata.java:28)

at com.sun.facelets.tag.jsf.ComponentHandler.apply(ComponentHandler.java:165)
...

Il semblerait que la balise index ne prenne pas en compte ma variable, et renseigne toujours NULL. Pourtant, un exemple est donn� sur cette page: http://wiki.apache.org/myfaces/Displ...ons_In_Columns

It seems that the index attribute doesn't accept my var. An exemple of the same code is given here: http://wiki.apache.org/myfaces/Display_Radio_Buttons_In_Columns

Thanks.
