In my opinion, the back button should work allways, becaus of the usability, and the developer should take care of what happens with data and so on.</p> <p>Anyway, does anybody have a solution for this?</p>enFri, 18 Sep 2015 04:53:58 -0400https://answers.axonivy.com/questions/1450/500-server-error-when-hitting-history-back-button-of-browser/1482<p>Here is a work around - You can deactivate the back button. Here is the code to add to the HTML page... It works in Html Dialogs. </p> &lt;script type="text/javascript"&gt; //for old browsers window.location.hash = "no-back-button"; window.location.hash = "Again-No-back-button"; window.onhashchange = function() { window.location.hash = "no-back-button"; } //for browsers that support HTML5 history.pushState(null, null, 'no-back-button'); window.addEventListener('popstate', function(event) { history.pushState(null, null, 'no-back-button'); }); &lt;/script&gt; <p><a href="http://forum.primefaces.org/viewtopic.php?f=3&amp;t=40503">http://forum.primefaces.org/viewtopic.php?f=3&amp;t=40503</a> </p>enricojlFri, 18 Sep 2015 04:53:58 -0400https://answers.axonivy.com/questions/1450/500-server-error-when-hitting-history-back-button-of-browser/1482
