I am using <p:ajax event="page" ... /> for a paginated p:dataTable

But the ajax request gets fired after the page is changed. How to do process the input elements in the page that was displayed previous to the page change?

In case the page changes and if you're using jQuery for ajax, try handling event using live() method.

The question was in the context of using something like

Code: Select all

<p:dataTable  id="qlisttbl" widgetVar="qlisttbl"  paginator="true" rows="1"   value="#{freeExamDeliveryAction.examToDeliver.questionCollection}" var="q">

                            <p:ajax event="page" process="somecomponentID"/>
This somecomponentID component content varies for each page. Hence when we switch to a different page (say from page 2 to page 5) and then again come back to page 2, I dont see the state saved and retained.
