---------------------------------
Milo, could you please add here link for Mojarra/MyFaces issues?
> render of 'c:' and 'fn:' is one click behind
> --------------------------------------------
>
> Key: RF-11803
> URL: https://issues.jboss.org/browse/RF-11803
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Environment: MyFaces 2.1.5, Tomcat 7.0.22, 4.1.0-20111204 from
> showcase
> Reporter: Milo van der Zee
> Assignee: Lukáš Fryč
> Priority: Minor
> Labels: render, waiting_on_user
>
> '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.
> MAG,
