    rich:progressBar does not work in my project

    Thomas Rademacher Newbie

      Hello,

      I have a jsf based application with jsf 1.2.12 and richfaces 3.3.2.SR1 and I want to integrate a rich:progressBar.

       

      In my myxhtml.xhtml I implemented a server side rich:progressBar. With the javascript function enableProgressBar() (see myjavascript.js) for the onclick-event I want to enable the progessbar. But I can not see a polling (interval="2000") my server in debug mode.

      When I set breakpoints in the functions AdmUserListViewBulkRemove::performDeletion() and ProgressBarBean:getCurrentValue(), first the function performDeletion() was called and after finishing the function getCurrentValue() was called.

       

      How can I set my progessbar to the state 'enable'?

      Thanks for your hints, Thomas
