Re: [rules-dev] ClassCastException: org.drools.reteoo.AlphaNode$AlphaMemory cannot be cast to org.drools.reteoo.BetaMemory

Hi Mark, I've done as much as possible on drools-docs-expert. "Major" changes were - the insertion of a few paragraphs for 3.3.8.2 JAXB Transformer - the addition (to 3.1.2, Building and Configuration...,) of a non-normative (!) XML Schema for ChangeSet - splitting 4.8.3, RHS, into "Usage" and the new "The modify Statement" I had the Chapter 5 split into a chapter and a section XML, restoring the lost images while you released the fix for the xml:base; so I kept the split because it may be needed anyway, in the future. I didn't manage to read chapters 6 through 8. One thing I couldn't ask on irc yesterday concerns the ancient change notices "new in 4.0"; so I decided to remove them. The new structure of "Expert" is certainly a big improvement. I propose to continue my reviews and incremental improvements, but I'd like to reach agreement about a few typesetting issues first. I'll be back with a list. Regards Wolfgang
