    poll with rerender problem

    bryan Newbie

      I have several tabs on a jsf/facelets page that I want to use the a4j:poll function to refresh the contents of the tab when data is updated in the application. The problem I am having is that the contents of the tabs are not being rendered until the first interval is reached. My problem started when I tied the enabled flag on the a4j:poll to a boolean variable on my action class. If I hard code enabled="true" the contents of the tab are rendered when the page loads. The problem is that I want to use a variable so I can toggle the enabled flag. Am I correct in trying to use the enabled flag to toggle the a4j:poll from rerendering? What is the difference between hard coding enabled="true" and setting it to a boolean variable with a value of true? (I also tried changing the boolean variable to a String with a value of "true" and no luck)

      Thanks in advance.
