Checkboxes remain set when looping over screen

Question

Hi there,
I have got a problem with some checkboxes on a BSP with MVC.
I am creating an extension for cProjects within a single tabStrip.
My BSP constist of several checkboxes and I want to loop over this screen for some times to collect data. For every call of the BSP I create a new instance, set page attributes and call the view in DO_REQUEST. The page attributes cause some checkboxes to be set. This works fine so far.
My problem is that checkboxes that were selected on the previous screen remain selected.
I think this happens because the checkboxes have the same names as those on previous screens.
How can I disable this behaviour? I would appreciate your help.

Hi Raja,
thanks for your friendly welcome!
My BSP is already stateless. It is for assigning test
types to components in a production project and for
assigning standards to these test types. So there are
some nested groups with checkboxes.
First I loop over some existing test types and standards which will be displayed as 'checked' and the checkboxes are disabled. This works great so far.

                text    = "Next"

  mv_counter = 0.
  loop at mt_test_types_available into ms_test_type_available.
  read table mt_test_types into ms_test_type with key task_type = ms_test_type_available-test_type.
  if ms_test_type is not initial.
  mv_counter = mv_counter + 1.

  loop at mt_standards_available into ms_standard_available.
  if ms_standard_available-test_type = ms_test_type-task_type and ms_component-task_type = ms_standard_available-task_type.
  read table mt_standards into ms_standard with key task_type = ms_standard_available-product_std parent_guid = ms_test_type-task_guid.

                          checked  = "TRUE"
                          disabled = "TRUE" />
          <br />
          <%
  clear ms_standard.
After displaying the already existing standards I also display other standards that are available for a component and might be selected.
else.
          %>
          <htmlb:checkbox id   = "<%= ms_standard_available-product_std %><%= mv_counter %>"
                          text = "<%= ms_standard_available-product_std %>"
                          key  = "<%= ms_test_type-task_type %>" />
          <br />
          <%

  endif.
  endloop.
          %>
          </td>
        </htmlb:groupBody>
      </htmlb:group>
      <%
  else.
After that I also loop over test types that are not existing yet. They and their corresponding standards can be selected in addition.
mv_counter = mv_counter + 1.
      %>
      <td valign="TOP">
      <htmlb:group width="110px" >

      <htmlb:textView text   = "<%= ms_test_type_available-test_type %>"
                      design = "EMPHASIZED" />
        </htmlb:groupHeader>
        <htmlb:groupBody>
          <%
  loop at mt_standards_available into ms_standard_available.
  if ms_standard_available-test_type = ms_test_type_available-test_type and ms_component-task_type = ms_standard_available-task_type.
          %>
          <htmlb:checkbox id   = "<%= ms_standard_available-product_std %><%= mv_counter %>"
                          text = "<%= ms_standard_available-product_std %>"
                          key  = "<%= ms_test_type_available-test_type %>" />
          <br />
          <%
  endif.
  endloop.
          %>
          </td>
        </htmlb:groupBody>
      </htmlb:group>
      </td>
      <%
  endif.
  endloop.
      %>
      </tr>
      </table>
    </htmlb:groupBody>
  </htmlb:group>
</xhtmlb:overflowContainer>
