Debugging shows that script renderer reacts to PostAddToViewEvent and does some
nasty modifications on children. I don't know yet where the problem is (in
trinidad or in RI) but iterating over defensive copy of children list in
_publishPostAddToViewEvent solves this problem.

>
> the base-task can only work when we change our UIXComponentBase's setParent()
> to trigger the new "PostAddToViewEvent" event.
> As this event subsystem doesn't come for free (in terms of PERF
> costs), I will try to get some numbers on the inclusion of the
> behavior.
> However, the benefit of the "relocatable resources" feature is that we
> don't need to worry about "duplicated" resources, as something like
> this:
> ...
> <h:outputScript target="body" name="fooBody.js"/>
> <h:outputScript target="body" name="fooBody.js"/>
> <h:outputScript target="body" name="fooBody.js"/>
> ...
> Is only added once to the particular *target*...
