The error-page Element

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 uncaught exception is thrown in updating a ZUML page (e.g., in an event listener). Each page is associated with an exception type, 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 examining the exception types individually. If none is found, it will show an alert message to the client by default.

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>

For more information, please refer to ZK Developer's Reference: Error Handling.
