There is a status page in my application that is used to report updated status information. I have used a4j:poll tag to re-render portions of this page every second. The refresh is working fine. I have a number of h:dataTable components that are being refreshed with a4j:poll. On the same page, there are h:commandLink components that are used to navigate to different part of the application. None of the other pages have AJAX controls.
My current issue is that although the re-renders work all right and navigation to other pages works properly most of the time, there are cases where, when I click on the command links, a blank page is rendered. I am pretty sure this condition in related to the use of the a4j:poll.
I am wondering if others have seen this type of behavior and if there are guidelines to avoid this. I would also like to know if there are ways to troubleshoot this problem to figure out what is going on.
I have used both RichFaces 3.1.5 and 3.2.0. Same results. I am using latest Sun RI (1.2_08) and latest JDK (JDK 6 update 6).
