Two managed beans in same jsp page

Question

Hello
First this could be a stupid question, but i just can't find a solutions on this problem.
I wondering that could it be a two managed beans in same jsp page, here is a example:
index.jsp
<t:commandLink disabled="#{listBean.currentPage == 1}" id="previous2" type="button" immediate="true" style="font-size:small" action="#{listBean.previousPage}">
<h:outputText value="Edellinen" id="prev"/>
</t:commandLink>
<t:commandLink disabled="#{listBean.currentPage == listBean.totalPages}" id="next2" type="button" immediate="true" style="font-size:small;" action="#{listBean.nextPage}">
<h:outputText value="Seuraava" id="next"/>
</t:commandLink>
then i have a dataTable like this:
<t:dataTable value="#{customerListBean.customerBeans}"
binding="#{customerListBean.dataTable}" preserveDataModel="true" style="text-align:left">
My problem is that when i push a commandLink it doesn't refresh a dataTable. Does anyone know a solution here or is this just a impossible way to do it?
Thanks for help.

Answer 1

when i push nextPage (commandLink) it's call action
and count a new range of dataset and after that it's
calls a method which is declared on subClass and that
method get a new data of database on given params.
and put it on DataTable.
So listBean is upper class and customerListBean
extends on ListBeanNo, it doesn't work that way as you expected. You have created two independent instances. They doesn't communicate automatically with each other or so. Just use one CustomerListBean instance and call the inherited methods of ListBean on the #{customerListBean} managed bean instance.
