The error-page Element



 <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>
