As I'm unfamiliar with OOP principles I don't feel bad if I ignore them. :-)
So long as using This doesn't expose any mechanical issues such as memory or
security problems then I'll probably stick with This. The CFC won't be
persistant or in any session/app scopes.
Simon, I'm interested in what you mean by setting them in the variables
scope and return them using separate getter methods? Does that mean
variables.myvar in a CFC is exposed to the parent page? I suspect you mean
something else.
Thanks,
Gary.
