I'm using JSF 1.2 + RichFaces 3.3.3Final on JBoss 7.2.0(EAP 6.1)

I'm getting the above error when accessing any JSF page.

How do I fix the ViewHandler error ?

1. Re: Illegal attempt to set ViewHandler after a response has been rendered

I found the solution to my issue. Posting it here so it may be beneficial for others also.

By default, JBoss7 uses the 2.0 JSF implementation. However old JSF 1.2 based libraries like openfaces have issues running within JSF2.0 environment. Need to force the app server to load JSF1.2 environment.
To have it use the JBoss 1.2 implementation, you need to add the following context parameter to your web.xml:
<context-param>
<param-name>org.jboss.jbossfaces.JSF_CONFIG_NAME</param-name>
<param-value>Mojarra-1.2</param-value>

</context-param>
This fixed the problem.
