Working on this ajax stuff, I got to wondering why we don't just have
id's implemented like forceId = true? Is there any reason why we
can't just have all id's set to the id the user specifies without
prepending stuff to them?
The spec allows ids to be duplicated as long as they are in different
naming containers.
In particular, it is possible to use
<f:subview>
<jsp:include .../>
</f:subview>
and not worry whether any of the ids in the included page are the same
as ids in the current page; a Subview is a naming container, so every
component in the included page has the subview's id prefixed to it. That
ensures that there are no id conflicts.
Prefixing ids with the enclosing naming container's id is also critical
in tables (a table is a naming container which pretends to have a
different id as its rowIndex changes, so that component in different
rows have different prefixes to distinguish them.
