[seam-dev] Re: PARAM_BUILD_BEFORE_RESTORE

[Shane Bryzak]

I tested by browsing to the login page, then killing JBossAS and 
restarting it (same effect as session timing out) yet still get the same 
exception.  My web.xml has the following entry:

    <context-param>
        <param-name>facelets.BUILD_BEFORE_RESTORE</param-name>
        <param-value>true</param-value>
    </context-param>

Here's the stack trace.  I checked the version of Facelets that we have 
in Seam and it's 1.1.15.B1.
