insulating a4j:region from causing page reload
Hello,
As in the code snippet below, I have a a4j:region containing an a4j:poll just like the poll clock example in the live demo (http://livedemo.exadel.com/richfaces-demo/richfaces/poll.jsf?c=poll&tab=usage). I have added a form node below with a dataTable in it. In the backing bean code which supplies the table (method: getFeedDataList) I have log4j statements which show from the console that the method is being accessed every 800ms - ie the same time my a4j:poll triggers an update for the server time from a different method in the same bean.
I've read the manual and looked at using a4j:regions (tried renderRegionOnly and selfRendered) and a4j:forms in different combinations but I cannot find a way to insulate the a4j:region which controls the clock from causing a reload of the whole page. Can anyone point out how I can do this?
Many thanks for any help in advance
Mark
