RE : Custom Components with child-components
Any way we could delegate the construction of the children component
tree to a JSP rather than building the tree programmatically?
Something like :
myComponent.getChildren().add(process("/myComponentBody.jsp"))
Allowing a mapping between pseudo-beans used in this JSP (like foo in
#{fooBean.bar}) and real beans that would be used by the client of our
component would also add a great deal of flexibility to our component
(kind of like myfaces aliasBean):
<!-- client.jsp -->
<myComponent fooBean="#{myRealBean}"/>
---------------------------
<!-- myComponentBody.jsp -->
<h:inputText value="#{fooBean.bar}"/>
This would greatly simplify development of reusable panels.

Option b is definitely the correct answer. To add a child:
myComponent.getChildren().add(childComponent);
