and the fulfill condition (
condition_2) could be one of the following:
It is used to specify when to create the child components. By default (i.e.,
fulfill is not specified), the child components are created right after its parent component, at the time the ZUML page is loaded.
If you want to defer the creation of the child components, you can specify the condition with the
fulfill attribute. The condition consists of the event name and, optionally, the target component's identifier or path. It means that the child elements won't be processed, until the event is received by, if specified, the target component. If the identifier is omitted, the same component is assumed.
If an EL expression is specified, it must return a component, an identifier or a path.
If URI (
a_uri) is specified, the ZUML document of the given URI will be loaded and rendered as children of the associated component. Notice that you could specify at most one URI in a fulfill attribute.
For more information, please refer to ZK Developer's Reference: On-demand Evaluation.
The onFulfill Event
After ZK applies the fulfill condition, i.e., creates all descendant components, it fires the
onFulfill event with an instance of FulfillEvent to notify the component for further processing if any.
For example, if you use the
wireVariables method of the Components class, you might have to call
wireVariables again to wire the new components in the
<div fulfill="b1.onClick, b2.onOpen" onFulfill="Components.wireVariables(self, controller)"> ... </div>
