Defer the Creation of Child Components


For sophisticated pages, the performance can be improved if we defer the creation of child components until they become visible. The simplest way to do this is by the use of the fulfill attribute. In the following example, the children of the second tab panel are created only if it becomes visible.

 1 <tabbox>
 2     <tabs>
 3         <tab label="Preload" selected="true"/>
 4         <tab id="tab2" label="OnDemand"/>
 5     </tabs>
 6     <tabpanels>
 7         <tabpanel>
 8 			This panel is pre-loaded since no fulfill specified
 9         </tabpanel>
10         <tabpanel fulfill="self.linkedTab.onSelect">
11 			This panel is loaded only if tab2 receives the onSelect event
12         </tabpanel>
13     </tabpanels>
14 </tabbox>
