title: DataModel must implement org.primefaces.model.SelectableDataModel when selection is enabled
body: <p>I was trying to implement one DataTable Editable with RowSelection enabled.</p>
  
  <p>But it is throwing out an exception:</p>
  
  <blockquote>
    <p>DataModel must implement org.primefaces.model.SelectableDataModel when
    selection is enabled.</p>
  </blockquote>
  
  <p>I implemented the DataModel in both the object class and the managed bean class but the error is the same. Now only a blank table appears for me. Please help.</p>
