<a:IncludeComponent>

AWIncludeComponent enables dynamic selection of a component (or element) to be switched in dynamically. This is a key enabler for extensible / meta-data-driven UIs.

Example:

<!-- Use the right kind of form for the selected object -->
<a:IncludeComponent name="$componentNameForSelectedObject" inspect="$selectedObject"/>

In this example, the containing component may implement as follows:

public String componentNameForSelectedObject() {
    return (selectedObject instanceof Project)
            ? "ProjectInspector"
            : "GenericInspector";
}

(Of course, a more extensible app would consult a registry or set of delegates to determine the appropriate component to return).

Note that IncludeComponent passes along any bindings that it doesn't recognize to the included component (like "inspect" in the example above) so the app can use component-specific bindings just as if the included component were being bound statically.

Bindings

name	The name of the component to include. (Can use awcomponentName if name is needed to be passed as binding to the included component).	String (get)
awcomponentName	Alternate for "name"	String (get)
awcomponentReference	Advanced. Used by elements like TabSet to switch in embeded component references (mined from the parent tags body). Should be used with awcomponent binding.	AWComponentReference (get)
awcomponent	Advanced. Used in concert with awcomponentReference to provide the context component for bindings of the componentReference.	AWComponentReference (get)
