Thanks for your assistance. I really appreciate the quick response. 

One thing I really hate. Is struggling with understanding a new framework. Reaching a blockage point, fighting with it for a few days. Then asking for help, only to find the answer myself, shortly after posting  a message that say "Hey I can't figure out how to do this".  I hate that.

My problem of course is that I'm not reading the book sequentially from start to finish. That would make too much sense, be to logical and take too long (that should all be read with a note of irony). Instead I'm jumping around reading a bit here and a bit there.. So I jumped to chapter 24. Where I read about Magritte and found my quote:

This is clearly the place to hook a database commit for example.

I went back scanned through the book again and found the whole section 12.6.2 Behavioral Decorations. Shortly there after I  had my code using SandstoneDB and saving records to the filesystem.

page 364, second paragraph from the end.

I actually do it on two different lines:

 editor := (person asComponent addValidatedForm). 

 editor onAnswer: [ :answer | answer isNil ifFalse: [answer doSave]].

I call my own save method here, rather then call the Sandstone save method so I can do any thing else that might be required before I save to the db.

Oh, where that only true. My full time day job is still java development. I'm just sneaking in a quick attempt to try and do a prototype proof of concept with smalltalk/seaside, with out anyone being the wiser and on my own time.  Yes, I have to say I'm enjoying this a great deal more than Java dev.
