As others are indicating, factories become more and more useful as your
application becomes more and more complex.
In the first app i built using CFC's, after about a year of iterations and
improvements, i had well over 1800 CreateObject() calls in the thing. One
day a problem arose because of
PS ... On the way to the post office to check my mail, i realized i forgot

Your approach of creating all your objects in Application.cfm and placing
them in application scope kind of encapsulates your object creation for now.
But this approach will break down the

By the power of Greyskull! Are you trying to take over the world with
your 1800 objects? ;-)
We use a lot
I do use this technique.
cfif NOT isDefined('application.layout') OR isDefined('url.appInit')
I just didn't want to take the time to write it out though. hahaha
Thanks for posting that though. I think there are a lot of people that
don't know that they need to do these sort of things.
Thanks
Why would I want to load an object into the application scope just to
load more objects? This is one more piece of code that has to be ran,
maintained, suck up processes, suck up memory, to explain Wouldn't
it be best to just keep it simple and call right to the CFC?
It sounds to me like
I have read a lot about people making their own objectFactory and I
still don't see the need for one. Can some one please give me a reason
why I would need to use one? So far I have yet to find a reason not to
call to the objects directly when I need them. My lack of
understanding makes me think
The real benefits I have found are:
1)
Objects are initialised in one place only, so if the init arguments change,
then I only need to change one piece of code.
2)
Objects are created in one place only, so if the location of the component
changes, then I only need to change one piece of code.

Application scope, is this just done in App.cfm or App.cfc? Thanks for any
guidance.

I am not one to give guidance since I am new to all this myself,

I think the idea is
Another reason why I did not use an object factory is because I noted
the fact that you have to register all the DAO's, gateways and beans
with the full path in Application.cfm. It seemed just as easy to
instantiate all of my objects directly in Application.cfm and assign
them to the application

But why not go ahead and get the job done with the initial load of the
application? Why wait for it to happen two page loads later?
If you initialize all of your objects with the start of your
application then the user will have to wait until the objects are all
initialized before they can
to explicitly reload your
objects, set the url variable reloadObjects.

I'm going to look for some decent example of a objectFactory and do
some testing to see if there is a performance hit.
That sounds like a great idea. Here is an objectFactory to look at and
compare with:

My experience has been thinking i only have a few objects so it's not
really worth the effort of building a factory. But i built one anyway
for the experience. But when i look at that first OOP project now, a
year later, i see my site which was originally going to have only 10
objects now has
22 matches
