Re: [jsr-314-open] Providing the ability to instantiate EzComp components in Java code
+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/...);
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 ;-)

Subject: Providing the ability to instantiate EzComp components in
Java code
To: jsr-314-comments(a)jcp.org
I feel there is value in the ability to instantiate an EzComp object
in Java so that a component tree can be built in a backing bean (or
other Class). JSF must be doing this in the background through
Facelets, so providing this ability in Java should not be too
difficult.
Referencing an object by its namespace should be sufficient:
UIComponent comp = Application.createComponent(FacesContext,
"http://java.sun.com/jsf/composite/mynamespace:component").
Attributes would be assigned via the normal method:
comp.getAttributes().put("rendered", false);
This would greatly extend the reach of EzComp objects.
Thanks,
Lincoln
