I like it ;-)

Oh don't get me wrong, I am all for it but we need to make it crystal
clear to new C2 users how this stuff is meant to go together or else we
will be answering a million emails on how to do old habits in this new

OK so my example was best dealt with using an action - is there a
UserValidationAction (not today) to show people...... how does the map
object get passed back.... etc.... I know this may be obvious to people
familliar with C2 but to newbies this stuff is going to fill our email

We need to make this VERY clear. For a user writing
<xsp-response:send-redirect location=""/> is simple,
taking something that simple away and not having an equivelent method is
a problem in my book.

So as another example what if we want to redirect to a value that is
returned from a database call... where the user wants to use esql
(beacuse it is *simple*) to retirve the value from the database? how is
that redirect passed back to the sitemap?

I hope this thread is helping people think about the users, not
developers, because at the end of the day we want more users than
developers using this solution.
