Re: NullPointerException in PartialPageUtils

I downloaded the war yesterday, this is what the pom.properties sais:

#Generated by Maven
#Sat Jan 20 14:10:38 GMT+00:00 2007
version=incubator-m1-SNAPSHOT
groupId=org.apache.myfaces.trinidad
artifactId=trinidad-demo

I'll probably try building trinidad from scratch tomorrow. Thanks so far,

JSF-Spring does not use any filters - but we use some more filters like
"MyFacesExtensionsFilter", etc. I ensured the trinidad filter being the
very first. Unfortunately that does not solve the problem. I tried out
the demo war from the snapshot but I also get an error after choosing
which demo I want to see (first post).

I'm a bit in the dark here ;).

Thanks for your help - that error can't be unsolvable!?
