Interface RenderAgent

All Superinterfaces:
Agent, OperationAgent
public interface RenderAgent extends OperationAgent

To render a child components of a data component that is not rendered yet. Listbox and Grid supports this operation.

Because of ZK will not render all sub-items at first, it just pre-loads first few items. Until a user scrolls the scroll bar down, it loads and renders subsequent items. You will retrieve an invalid child component before it's rendered. Hence if you want to manipulate a not-rendered child component, you have to render it first.
