I've made a modification to the file zend/ProgressBar/Adapter/Adapter.php, cause it don't work with ajax calls, just executing the large proccess in a <iframe> tag.
With this modification, if you set the property ajaxAccess to false (using the setAjaxAccess()), the component will work in normal form (as the default zend component), bur if you set it to true, it will work with ajax calls, made by de same
page.in the attachments is the file updated, and a example of use, wtih a ExtJS library ajax call.
I hope it can be usefull to you. Any doubt, please mail me.
