Yup, it can be done using Java -- either by using [i]another[/i] Java-based custom component, or making our own component Java-based.
I just don't know if it can be done in a pure composite component, without any Java involved.
Of course, there's nothing wrong using Java. I actually like it more in certain cases. I'm simply curious whether there's [i]built-in[/i] functionality in JSF2 which allows us to perform component lookup by id (not by clientId).
