CAF Model
The client-side CAF.model(id) creates a model object for each control rendered on a page. All control IDs used by the Composite Application Framework client-side model are client-side IDs which are different from and related to server-side IDs developers specify at design-time. Client-side IDs are generated at run-time. You can map client-side IDs in one of two ways:
In your Java code by calling the
getClientId() method of the
javax.faces.component.UIComponent object. This method gets the client-side ID of the control represented by the
UIComponent object.
In a binding expression, by referencing the
clientId content provider on any page bean,
#{activePageBean.clientIds['myControlId']}. This approach produces a client-side ID for any given server-side ID.
The client-side model objects produced by the CAF.model() enable manipulating controls without knowledge of the controls' DHTML implementation. The model itself holds no state; every invocation of CAF.model() creates a new model instance. The model simply exposes methods that enable examining and modifying the state of the modeled control.
All models have three standard, read-only properties:
ID
Element - controls the primary HTML element
form.ID - the control’s client-side ID
Form is the control's containing HTML form element when the control is contained by a form.
