dataTable rendering problem

[fuligj]

Hello!

I' am using richfaces 3.1.2GA. When the dataTable rendered in a page with value tag null and then this variable become a not null value and the dataTable is in effect reRendered, none of actions in table's column executable.
What could be wrong?
Thank you and sorry for my bad english!

Thanks, for feedback!
So here is the JSF page source:

<h:form>
 <a4j:commandButton value="Set value to variable list" reRender="dataTable">
 <a4j:actionparam name="p" value="#{tb.items}" assignTo="#{list}"/>
 </a4j:commandButton>
 <rich:dataTable value="#{list}" id="dataTable">
 <rich:column>
 <a4j:commandButton value="SubCommand" reRender="text">
 <a4j:actionparam name="p1" value="Alex" assignTo="#{p1}"/>
 </a4j:commandButton>
 </rich:column>
 </rich:dataTable>
 <h:outputText value="#{p1}" id="text"/>
 </h:form>

Bean code:

package test;

import java.util.List;
import java.util.ArrayList;

public class TestBean {

 List items = null;

 public List getItems() {
 items = new ArrayList();
 items.add(1);
 return items;
 }
}

When I click "Set value to variable list" button the "list" variable become a new value and the datatable in effect rendered. Now I click the "SubCommand" button, but nothing changes.
When I take out the "SubCommand" button from datatable, the outputText become the value "Alex".

Thank You!
Best regards!
