---------------------------------

Milo, you could surely file bug against JSF impls, you just need minimize the sample to use plain JSF tags.

> 'c:' and 'fn:' is rendered differently from previous versions.
> When clicking the inc and dec buttons in the example you can see that the field contents are updates each click but the number of fields is not (comma at the end when pressing 'dec'. Pressing 'render' then fixes the output.
> When using a function to render it works fine. Even though the function does not do much.
