Component binding inside h:dataTable fails

Question

Hi,
I'd like to create a component binding for each commandLink to a distinct child bean inside an h:dataTable like so:
<h:dataTable value="#{parent.children}" var="child">
    <h:column>
        <h:commandLink binding="#{child.command1}" value="do it to it for #{child}" action="#{child.action}"/>
    </h:column>
</h:dataTable>But whenever I try to render this page I get an exception stating that "child is null" and binding cannot be performed. If I remove 'binding="#{child.command1}"', however, everything works fine. I guess this is happening because 'var="child"' in h:dataTable gets evaluated after bindings are created. How can I get around that - I really need to be able to refer distinctly refer to UIComponents in each row.
Confused...
thanks

I created a seperate class to handle the requests ActivationRequestBuilder and put the code in there .
if you want to refer to each row in the backing bean .
create a variable of type HtmlDataTable .
private HtmlDataTable tenantDataTable;
set up accessor and mutator methods for this variable.
In your jsp in the DataTable
<h:dataTable binding="#{activationRequestBuilder.tenantDataTable}"
<h:commandLink title="Delete Tenant section"
immediate="true" action="#{activationRequestBuilder.deleteTenantLocationSection}">
public String deleteTenantLocationSection(){
(TenantLocationRecordBean) this.getTenantDataTable().getRowData();
This is just snippets of code but you should get the idea of what I have done here .I had multiple sections in a page so each row was a TenantLocationRecordBean .
