Re: HELP NEEDED with Auth "Component" in Views; Fatal error: (While using Auth component inside a helper)

Thanks Sam, it's clearer now...but still struggling with Acl; I was
confused when I hear the word "populate" a general term. In oracle, I
populated db/tables/sql scripts in a batch file, last time. So it
brought me a meaning of the same when I hear it again. Now I know it
could mean using command line and here it's Bake. But I created the
tables already, is there a measurement to check if the tables are
correctly "populated" ? I may have to drop the 3 tables I created
earlier..and re-do starting from tutorial Acl(cookbook tutorial)
again/ the link you've sent to me. Will check on it, now.

Regards,

Maxim
