JBoss Seam + Facelets + Richfaces Tree StateWriter error

[gingming]

Originally posted in the JBoss Seam forum but no one seem to be able to help me.

I'm getting the following error once I tried to use the Richfaces Tree component:

java.lang.ClassCastException: com.sun.facelets.StateWriter

My environment is Java 5, Tomcat 5.5.20, JSF 1.2_03, Facelets 1.1.11, JBoss Seam 1.2.0_patch1, JBoss Richfaces 3.0.0, Ajax4jsf 1.1.0


I tried to use the Richfaces dataList and it works, so I guess my configuration for Richfaces is correct. May I know if anyone has successfully used the Tree and TreeNode of the latest Richfaces under JBoss Seam?

Thanks for your help.

check that you have no FaceletsViewHandler declared twice. (in faces-config and web.xml). Be sure, it is in the web.xml, not in the faces-config

I have the same problem. I use Glassfish Beta, JSF1.2 RI, Facelets 1.1.11, Ajax4JSF 1.1.0.

To tell the truth I can't see any mistake in configuration. But I can't resolve problem with StateWriter.

Hello!

The same problem has been reported for 1.2_02 JSF. That's StateWriter bug. It has been fixed in 1.2_04 JSF version. Please try to update!

[alexanderbelov]

Thank you, nbelaevski.

This problem is resolved.
