title: Spring datagrid with checkboxes
body: <p>I have a web-application in spring where tasks should be assigned to workers (say programmers). </p>
  
  <ol>
  <li>the application should be able to list tasks (unassigned tasks) in a grid</li>
  <li>On another side, the application should list workers (say programmers) </li>
  <li>the manager should be able to choose select tasks (or checking), and choose workers to whom he/she wishes to assign selected tasks</li>
  <li>hit submit button to assign selected tasks to chosen workers.</li>
  </ol>
  
  <p>Now, form processing with spring is processed <code>onSubmit(..., Command command, ...)</code> by binding a command (in most of cases Model classes) to the form. How can I implement the functionality above,  given 2 lists (one for workers and another for tasks). I appreciate any idea, link to a resource or a link to the same question as mine. </p>
