Only through experience I could offer this advice (aka 'been there, done that' ;-) I'm quite fresh to Seam as well (3 weeks or so), and it still has a lot of intricacies...
Yes, Sammy.
The docs are excellent for an Open Source project!!
They do still however have a slant towards to the more knowledgebale user!
They assume we know stuff!
Still the best docs I have found on an open source project anywhere.
And the suport you do get from these forums make most commercial organisations look like amatures!
Me Thinks we should have a gotcha section (I did post a gotcha on these forums a short while after I started) or an open page on teh wiki where we can post gotchas ourselves!
The http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamProblemsFAQ is a good place to post these things :)
Pete .. thats great its editable.
Thanks.
Will update when I get back 2nite.
