title: <rich:datatable> and <rich:datascroller> problem
body: <p>I am developing a Seam-Jsfv1.2-EJB3 web app.
  I have a datatable and checkboxes in each row. Moreover, I have a datascroller at the bottom of my table as well. </p>
  
  <p>My problem is when I click the next page number from the scroller, the selected checkboxes at the first page of the datatable is gone. I mean, even if they were selected, clicking the next page make them deselected. I see it by going back to the first page again by clicking the scroller.</p>
  
  <p>Do you have any idea about that problem?
  In order to clearify my case, I attached my code below:</p>
  
  <pre><code>&lt;rich:dataTable
              id="apiV2ProductList" rows="10" var="_apiV2Product"
              value="#{apiV2ProductList.resultList}"
              rendered="#{not empty apiV2ProductList.resultList}" reRender="ds"&gt;
              &lt;rich:column&gt;
                  &lt;f:facet name="header"&gt; 
                      &lt;h:selectBooleanCheckbox id="selectionCheckAll" onclick="selectAll()" /&gt; 
                  &lt;/f:facet&gt;
                  &lt;h:selectBooleanCheckbox id="selectionCheck" onclick="increase(this)" value="#{_apiV2Product.selectValue}" &gt;  
                  &lt;/h:selectBooleanCheckbox&gt;
              &lt;/rich:column&gt;
  </code></pre>
  
  <p>...</p>
  
  <pre><code>&lt;f:facet name="footer"&gt;
                  &lt;rich:datascroller id="ds" renderIfSinglePage="false"&gt;
                  &lt;/rich:datascroller&gt;
              &lt;/f:facet&gt;
  </code></pre>
  
  <p>Many thanks in advance.
