Getting Static Data in Footer

Question

Hi all,
I have a PO report where I have to print Total Sum(which is coming from a tag at header level) of each PO lines in footer. For this I have used template and call that template in the footer section as suggested by Paul.Now the problem is the Total Sum column in the footer is holding a static value for each PO which is the Total of the last PO in the loop.But I have defined the template within the for loop of the PO loop.Can anybody kindly help ?
Thanks in advance
Sanjay

Then maybe something like this?
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Date;
public class RunnableWithPreviousState implements Runnable {
    private static class State {
     public Date startTime, endTime;
     public State() {
         startTime = new Date();
    private static List<RunnableWithPreviousState> runnables = Collections
         .synchronizedList(new ArrayList<RunnableWithPreviousState>());
    private State previousState, myState;
    @Override
    public void run() {
     myState = new State();
     runnables.add(this);
     int index = runnables.indexOf(this);
     if (index > 0) {
         index -= 1;
         previousState = runnables.get(index).myState;
     if (previousState != null) {
         // inspect previousState
     // do other processing
     myState.endTime = new Date();
}Piet
