[jsr-314-open] Providing the ability to instantiate EzComp components in Java code

[Norbert Truchsess]

+1 from my side.

I wander whether we even might go a step further and allow to optionally
assign a 'real' UIComponent-class to an EzComp-Component (one that has
JavaBean getter/setter methods instead of the untyped attribute-map
only).

Then one could do the following in java:

MyFancyUIComponent comp =
(MyFancyUIComponent)Application.createComponent("http://java.sun.com/jsf/composite/myfancynamespace:component");

comp.setMyAttribute(myAttributeTypedObject);

..

Of course when just using the EzComp-component in xhtml the UIComponent
being created by the Facelet would by of the same type.

That would make EzComp-components look indistinguishable from a 'real'
UIComponent in java ;-)
