AComponent Class

This is the abstract class for all page controls. A page control is a single input/output component on an web page. One example of a control is the datepicker. For each instance of the datepicker on a single page, you need an instance of an AComponent. Components of like controls are managed through a single component manger. So, on a single page you might have 3 datepickers (3 instances of AComponent) all managed by a single datepicker manager. If you were to have other types of controls on that same page, you would need an instance of the appropriate componetent manager for those controls. The Page manager aggregates all instances of component mangers and provides access to page specific information that might be relevant to controls (i.e. locale and timezone). In summary: Component - Might have many on a page (i.e. datepicker). Note: There is really no difference between a "component" and a "control." Component Manager - One per type of component on a page. Page Manager - Only one per page. Aggregates all the component managers. How is the component manager differnt from the page manager? Why have both? The component manager serves two funtions. First, it aggregates like components. Second, it handles the printing of page-level content (contrast with component-level content.) Consider the datepicker example again. If you have 2 datepickers on one page, there is data that needs to be outputted once (page-level) and data that needs to be outputted once for each datepicker (component-level). One special note about the page-controls framework... It assumes that the client will be using the HTTP Session for state management. Given this, the client needs to have implemented a good HTTP Session mangment strategy that will release old or unused objects. See the documentation on Activity Spaces for such a framework.
