Hello, I was updating my Pier installation (using Pier-Seaside-lr.182 and others), it stumbled at PRPieronfiguration>>ancestors ^ Array with: WARenderConfiguration new not knowing the class WARenderConfiguration. Replacing this with WARenderLoopConfiguration works OK so far. I am running seaside 2.7b1. Looks like the ancestors method comes from Pier-Seaside-lr.182. Maybe WARenderLoopConfiguration got renamed to WARenderConfiguration in Seaside 2.8? Is it OK to use WARenderLoopConfiguration here? If not, where can I get WARenderConfiguration ? best regards Matthias _______________________________________________ SmallWiki, Magritte, Pier and Related Tools ... https://www.iam.unibe.ch/mailman/listinfo/smallwiki
