communication from scriptlet to jsf managed bean is not work

[anil3379]

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="#{HeaderBean.screenID}"> </h:outputText>

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

Please suggest me on this.

Yes, that is the expected behavior. You have effectively re-created the old JSF 1.1 problem with looping. However, this is fixed in JSF 1.2/JSP 2.1 (JBoss AS 4.2 and AS 5.0). But, you need to use a JSTL or JSF tag.

See problem: http://onjava.com/pub/a/onjava/2004/06/09/jsf.html
Fix in JSF 1.2: http://java.sun.com/developer/technicalArticles/J2EE/jsf_12/

You should never use scriptlets. They are considered bad practice.

For this, I suggest using the JSTL c:forEach tag. But if you really want to do things the right way, use Faceletes instead of JSP.

Hi stan,

Thanks for your reply. Here I have 2 problems.

- mix with jsf and JSTL for loop is not working.
- I need to put this fix in many places in my application. if I use facelets.I will have to change the type to .xhtml and it requires many modifications to my application.

Thanks,
Anil

This works and it has always worked since JBoss AS 4.2. You must be doing something wrong.

There is no getting around the fact that you must fix your broken code. You would benefit greatly from Facelets, but it's understandable if you can't make the switch.
