title: ace:dataTable to select multiple rows via the shift key in ICEFACES
body: <p>I am working on icefaces ACE Components and currently i am using ace:datatable.
  i am using below code </p>
  
  <pre><code> &lt;ace:dataTable var="invoice"  value="#{applicationBean.invoices}"          
        id="dataTableId" rows="10" paginator="true" height="350" paginatorPosition="bottom" page="1" 
  selectionMode="multiple" emptyMessage="There are no search results"
   pageCount="4" currentPageReportTemplate="Showing {startRecord}-{endRecord} out of {totalRecords}" 
  </code></pre>
  
  <p>i am able to see the data on my table. my problem is suppose there are 10 rows on table and if i select 2nd and pressed shift key and i select 5th rows then it should select 2 to 5 rows ....but its not working in my case. Is there any table attribute do i need to add or any other alternative component or any javascript i need to write for this please suggest me..</p>
