[seam-dev] Re: PARAM_BUILD_BEFORE_RESTORE

[Dan Allen]

Do you have this context parameter as well?

    <context-param>
        <param-name>com.sun.faces.disableVersionTracking</param-name>
        <param-value>true</param-value>
    </context-param>

I'm not sure this makes a difference, but it has something to do with
JSF detecting the wrong version of JSF due to RichFaces
faces-config.xml files on the classpath. When JSF is not working in
1.2 mode, it handles the restore logic differently. Check with this
enabled and report the results.
