render of 'c:' and 'fn:' is one click behind
--------------------------------------------
Key: MYFACES-3436
URL: https://issues.apache.org/jira/browse/MYFACES-3436
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 2.1.5
Environment: Tomcat 7.0.23, RichFaces 4.1.0-final, MyFaces 2.1.5
Reporter: Milo van der Zee
'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,
Milo

With function to render:

Without RichFaces:
<h:commandButton value="dec"

<f:ajax event="click" render="counter panel"/>
</h:commandButton>
<h:commandButton value="inc"
actionListener="#{testBean.incCounter()}">

Manual render:
<a4j:commandButton value="render" render="counter, panel"/>
