Having upgraded to Seam 2.1.0.SP, I am sudddenly getting NullPointerException on String page paramters.
I use some page paramters just to pass on to next page via page navigation, like below, but now doesnt like evaluating parameter anymore:
<page ...>
<param name="courseSysCourseIdList"/>
<navigation from-action="#{courseSysCourseAction.editCourseAction}">
<rule if-outcome="valid">
<redirect view-id="#{'orgUserAuthenticated.isLicensee'}">
<param name="courseSysCourseId" value="#{courseSysCourseIdList}"/>
</redirect>
</rule>
</navigation>
</page>

In .page.xml define it like this, without value attribute:
<param name="courseSysCourseIdList"/>
then use it in page navigation like this:
<param name="courseSysCourseId" value="#{courseSysCourseIdList}"/>
There is a known bug in Seam 2.1 regarding the use of page parameters on redirects. It seems to affect multiple usage scenarios, so likely there is a missing bit of code that is causing a ripple effect. I am working on it today and thus is expected to be part of 2.1.1. I will validate your problem is resolved.

As it turns out, the problem you were seeing was a result of a bug in the hot deploy mechanism. This will be fixed in 2.1.1.

Dan thank you for looking into it. I can now look forward to 2.1.1 release.
I am using SEAM 2.1.1 GA and RichFaces 3.3 and get this failure after upgrading RichFaces 3.2 to RichFaces 3.3:
Any help?
