Hi!

why not getElementsByName[0] ?

Well, in general document.getElementById is both faster and more elegant.

So in this case, rendering this component with id=clientId seems reasonable.

Hmm..but it is possible that there are multiple "view state" fields in
the page, one per form. So perhaps using "getElementsByName" is a good
idea in this specific case.
And also ensure that every ViewState will be replaced and not only the first [0] one. When you do have multiple JSF forms (which is valid) each ViewState needs to be replaced.

Ciao,
Mario
