#{index} of datatable

[nimo22]

How can I obtain the actual index of a row in a datatable?

something like?

<rich:extendedDataTable rowKeyVar="#{index}" .../>

<rich:column >
#{index}
</rich:column>

</rich:extendedDataTable>

yes this code should works.

it does not work and I do not know why (RF 3.3.0).

However {index} is not a defined property in my managed bean, but I guess, this is not the problem?!

<rich:dataTable value="#{viewDatas}" var="_a" rowKeyVar="#{index}" >

 <rich:column label="index">
 <f:facet name="header">
 <h:outputText value="Index"/>
 </f:facet>
 <h:outputText value ="#{index}"/>
 </rich:column>

 </rich:dataTable>

I tried it also with that:

<a4j:repeat value="#{myDatas}" var="d" rowKeyVar="#{index}">

 <h:outputText value="#{d.prop} #{index}"/>

 </a4j:repeat>

it does not work, strange.

oh was my fault. this works:

<a4j:repeat value="#{myDatas}" var="d" rowKeyVar="i">
#{i}
</a4j:repeat>
