There's an issue described on Bea site about IllegalStateException & MyFaces but I think that's not the reason of this cause. I'll check and let you know

Hi All,

I am using Rich Faces 3.2.1 With Myfaces 1.2.3 on weblogic 10 MP1.

I am trying to display simple page with Rich faces (Ajax4JSF) component.

I am always getting Following exception.

When i remove Rich faces filter from web.xml, my page is displaying properly with out Ajax capabilities. But i need ajax capabilities.

How to fix this problem, please let me know.

Dwaraka.

Dwaraka,

I've solved the problem on WL 10.3 by replacing out-of-date JSF with new version: https://jira.jboss.org/jira/browse/RF-4415

Hi Belaevski,

Thanks for your quick reply.
We already tried with Sun RI 1.2_07. My sample application working fine. I have to resolve this problem using Myfaces implementation.

Is there a way to solve this problem using Myfaces on weblogic 10 MP1?

Regards,
Dwaraka.

Hi Perhaps the Seam BEA10 instructions can be helpful (as richfaces is included in Seam 2.x.x)
