Since a few months we are having occasional errors in showing messageboxes in our web application. First of all, we are actually using ZK version 5.0.9 on a weblogic server version 10.3.5 The error doesn't happen sistematically but appears after a variable period of time (generally more than a week) on just 1 or 2 of the 6 machines where the application runs, once the error has appeared it is generated every time the method Messagebox.show is invoked all over the application (on that specific machine) and the only way to make it work again is restarting the server on that machine. Attached the stacktrace generated in case of error. We would be grateful for any possible suggestion!
