Syntax:
<error-page> <device-type>a_device_type|ajax</device-type> <exception-type>a_class_name</exception-type> <location>a_uri</location> </error-page>
It specifies an error page used when an un-caught exception is thrown in updating a ZUML page (e.g., in an event listener). Each page is associated with an exception type, aka, a class deriving from java.lang.Throwable. You can specify multiple error pages, each with a different exception type. When an error occurs, ZK searches the proper error page by examing the exception type one-by-one. If none is found, it shows, by default, an alert message at the client.
The device-type element is optional. If omitted, ajax is assumed.
For example,
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/WEB-INF/sys/error.zul</location>
</error-page>
