<rich:effect> Resource not registered problem.

[fs2007]

I put this line in my .xhtml from the richfaces demo (Running richfaces on JBoss Portal 2.6)

<rich:panel>
 <rich:effect event="onmouseout" type="Opacity" params="duration:0.8,from:1.0,to:0.3" />

 .... panel content ....
</rich:panel>

I kept getting "Resource not registered : scripts/scriptaculous/*.js" (for a few of the scriptaculous js files) despite having richfaces-impl-3.1.0.jar in my WEB-INF/lib

Is there anything else I'd have to put in my portlet to make this work?

Thanks.

Do nothing. Or use 3.1.1-SNAPSHOT if you do not want to see this harmless exceptions.
