5 onCreate added in doAfterCompose not running - ID: 2808240

Last Update: Comment added ( henrichen )

Details:

If you use doAfterCompose to add an onCreate event listener to a component
it wont run. If you add an empty zscript onCreate to the component then the
onCreate registered in the doAfterCompose will run. The attached demo
project has two files addListenerTest1.zul and addListenerTest2.zul which
use the same TestComposer which programmatically adds onCreate. On version
has no zsript onCreate and the other has empty zkscript onCreate.

Date: 2009-06-22 06:25 Sender: henrichen The UiEngineImpl post onCreate event one by one if there was onCreate listener when parse the zul file; thus the child components is already "parsed" and therefore "miss" the opportunity to post the event (since eventlistener is added later in doAfterCompose). A "formal" way might be implement FullComposer in the composer so doAfterCompose is called with each child component and make the timing correct. Otherwise, have to put an empty onCreate to make UiEngineImpl to post the event, then the later added event listener in doAfterCompose() will be called in event handling phase. We will not change the implementation of UiEngineImpl because of the backward compatibility.
