doHandleEvent

public EventResult doHandleEvent(BajaContext context,
                                 Page page,
                                 PageEvent event)
                          throws java.lang.Throwable

Description copied from class: AbstractDataEventHandler

Handle an event. Clients return an EventResult object that encapsulates the resulsts. If handleEvent() returns null, the PageBroker will simply redisplay the same page. Otherwise, the result will be passed to the PageFlowEngine to determine the Page to render.

Clients should implement this method, instead of handleEvent, to perform the actual event handling logic.

Note: while the Page object is mutable, any calls that set properties, etc., will be ignored unless the Page is itself returned inside the EventResult.

Overrides:

doHandleEvent in class AbstractDataEventHandler

Following copied from class: oracle.cabo.servlet.event.AbstractDataEventHandler

Parameters:

context - the BajaContext

page - the page the client is requesting

event - the event on that page, or null if the client is just requesting a page display

Returns:

an object encapsulating results of this event

Throws:

java.lang.Throwable - if any processing of the event fails
