Hello Guys

I have been having this issue with combobox throwing unusual exception out of no where, it worked flawlessly still does, when a user chooses something out of combobox, it throws an exception. When I used to face this issue before, I just removed the ZK libraries and readded then it worked without this issue. The zul page, controller and thrown exception located below. I need your assistance in this issue. P.S. I Use zk 7.0.2 EE and tomcat ibm websphere servers

Thanks

Hello Guys

I have been having this issue with combobox throwing unusual exception out of no where, it worked flawlessly still does, when a user chooses something out of combobox, it throws an exception. When I used to face this issue before, I just removed the ZK libraries and readded then it worked without this issue. The zul page, controller and thrown exception located below. I need your assistance in this issue. P.S. I Use zk 7.0.2 EE and tomcat ibm websphere servers

Thanks
