| Interface for any kind of object (typically, a component) that can provide a
ClientElement.getClientId() client-side id , typically used in the generation of client-side
(JavaScript) logic. For components, the client id will be null or innaccurate until after the
component has rendered itself. Inside of any kind of loop, the clientId property is only accurate
just after the component has rendered, and before it renders again.
Some components must be configured to provide a client id. In many cases, the client id matches
the component's
ComponentResourcesCommon.getId component id , typically passed through
PageRenderSupport.allocateClientId(String) to ensure uniqueness.
