communitcation from scriptlet to jsf managed bean is not working

Here is the sample code.
<%

for (int i = 1; i < 5; i++) {
HeaderBean header = new HeaderBean();
header.setScreenID("" + i);
application.setAttribute("HeaderBean", header);
%>

<h:outputText value="#

"> </h:outputText>

<%}%>

its always displaying the last value,the out put is "4444" instead of "1234". Is this expected behavior?
