Hello All,
My introduction to OOP in CF is a rewrite of a CF5 application generator in
CFMX 7. I have a pretty good domain object model but am having trouble
finding best practices for the UI.
All of the controller (index.cfm) and model (various cfc's with a simple
façade abstracting the
Hello All,
I'm sure this must be an easy one, but I'm a little stumped.
I have a rules engine that allows non-technical admins to create rules for
things like what page template to use for a given page request. The rules
support nesting and precedence with an if/then/else construction. They are
on pages with lots of content blocks.

Hello All,
My introduction to OOP in CF
End user uses a web based admin to generate business rules (Simple if
variable operator variable/static then action else action endif with
support for nesting and precedence). They also get a rebuild button which
takes the individual elements (variable, operator, action, etc.) and
concatenates
to make it quite
performant, especially on pages with lots of content blocks.

Right. As Haikal points out, the value of interfaces (and strong typing for
that matter) is that it forces programmers to write more completely
self-describing code. If you HAVE to specify an interface, it is easier for
other programmers to understand what methods a class can implement.

Peter
