In our Production ZK6 application running on Tomcat7, we have started to see our logs filled with this exception. It does not mention our code really in the exception so I write here today to see if anyone at ZK understands what this error "Unable to activate destroyed desktop" might mean. Thank you!

SEVERE: Exception Processing ErrorPage[errorCode=500, location=/zkau/web/org/ourapp/ui/zk/errorLoading.zul]
org.zkoss.zk.ui.DesktopUnavailableException: Unable to activate destroyed desktop, [Desktop z_9di:/org/ourcompany/ourapp/security/impl/loginWindow.zul]

Hi,

From the javadoc It denotes the desktop being accessed is no longer available. It is typical thrown when a server push is executing and the desktop is removed by the client.

But it's hard to track the real problem with the stack track, could you provide more details on when this exception occurs? General description of your use case implementation or sample code would help us to find the problem.

Thanks
