Prob in accessing DataSourece value from netui-data:repeater after submit

Question

HI all,
          I am new to this WLWS. PLease guide me in the following scenario:
          I am retrieving an array of records (activityDetails[]) from a Db control and setting this to the datasource property of a netui-data:repeater. Basically I am populating a list of records in my jsp page which works fine.
          But When a submit the page, I am not able to access that array of records from the action method difined in my controller.jpf file, even though I have declared the array in the Form bean.
          And I am not sure if have set the proper datasource for the checkBox defined within the records. The purpose of this checkbox is to select the records form the list to be saved in the database. Is there any better way of achieving the same.
          It's throwing Null pointer exception in the method called
          doProcess.
          Here is the related code:
          activities.jsp
          <netui:button type="submit" tagId="btnSave" value="Save" styleClass="btn" action="doProcess"/>
          <netui:button tagId="btnPrint" value="Print" styleClass="btn" onClick="doPrint()"/>
                                   </td>
                              </tr>
          <netui-data:repeater dataSource="{actionForm.activityDetails}" >
          <netui-data:getData resultId="pkg" value="{container.item.pkg_header_id}" />
          <tr bordercolor="#A8A8A8" >
          <%
          if (pageContext.getAttribute("pkg") == null)
          %>
          <td><netui:content value=" "/></td>
          <%
          else
          %>
          <td><netui:checkBox dataSource="{container.item.activity_id}"/>
          <%
          %>
          <td><netui:content value="{container.item.prt_no}"/> </td>
          <td><netui:content value="{container.item.activity_num}"/> </td>
          <td><netui:content value="{container.item.frc_acct_code}"/> </td>
          <td><netui:content value="{container.item.frc_acct_code}"/> </td>
          <td><netui:content value="{container.item.status_code}"/> </td>
          <td><netui:content value="{container.item.location_code}"/> </td>
          <td><netui:content value="{container.item.task_code}"/> </td>
          <td><netui:content value=" "/> </td>
          <td><netui:content value="{container.item.wpid}"/> </td>
          <td><netui:content value="{container.item.original_qty}"/> </td>
          <td><netui:content value="{container.item.act_obj_hrs}"/> </td>
          <td><netui:content value="{container.item.act_actual_hrs}"/> </td>
          <td><netui:content value="{container.item.act_rmng_hrs}"/> </td>
          <td><netui:content value="{container.item.act_rmrk}"/> </td>
          </tr>
          </netui-data:repeater>
          </table>
          </netui:form>
          </netui-template:section>
          </netui-template:template>
          Here is the .jpf file
          public class VSchedController extends PageFlowController
          * @common:control
          private custom.ConstSched constSched;
          private ActivityDetails[] activityDetails;
          * @jpf:action
          * @jpf:forward name="index" path="index.jsp"
          * @jpf:forward name = "success" path = "packageActivities.jsp"
          protected Forward begin(PackageSchedForm form) throws SQLException
          HttpSession s = getRequest().getSession(false);
          int jobID = (s.getAttribute("JOB_ID") != null) ? Integer.parseInt(s.getAttribute("JOB_ID").toString()) : 0;
          if (jobID == 0) jobID = 6;
          setActivityDetails(constSched.getAllActivities(jobID));
          form.setActivityDetails(activityDetails);
          return new Forward("success");
          * @jpf:action
          * @jpf:forward name="success" path="packageActivities.jsp"
          protected Forward doProcess(PackageSchedForm form) throws SQLException
          System.out.println("----------------------------------------");
          System.out.println("ActivityDetails is null ? " + (form.activityDetails == null));
          for(int i=0; i < 6; i++)
          try
          System.out.println("Checked -> " + form.activityDetails.activity_id);
          catch(Exception e)
          System.out.println(i);
          System.out.println("----------------------------------------");
          return new Forward("success");
          public ActivityDetails[] getActivityDetails()
          return this.activityDetails;
          public void setActivityDetails(ActivityDetails[] activityDetails)
          this.activityDetails = activityDetails;
          * FormData get and set methods may be overwritten by the Form Bean editor.
          public static class PackageSchedForm extends FormData
          private ActivityDetails[] activityDetails;
          public ActivityDetails[] getActivityDetails()
          return this.activityDetails;
          public void setActivityDetails(ActivityDetails[] activityDetails)
          this.activityDetails = activityDetails;

Personally, I have had a hard time doing what you are asking for using netui tags. I have had the same case, and asked the person in my team to just return a collection of value objects and then iterate through it without the repeater tag. To use the checkbox, I have had to use a String[].
