The problem here is, based on the option selected from drop down, i have to display the second row and this is working but when i submit the form.
in bean all the values coming as null. even validation is not working. if i remove the <a4j:outputpanel> values are available in bean, but rendering is not working properly. could somebody help me on this. thanks in advance.
