Re: CFC in application scope....or else?
Thanks for all the help. Meanwhile I played with LightWire to get a feel of true IoC. I used 2 cfc, and wired them together. Product CFC and a tax calculator CFC. Product CFC depended on tax calculator to exist. I got it now, I can make OO objects/CFC's which can be easily re-used in another application, or other CFC's. So I write less CFC's... ~| ColdFusion 8 - Build next generation apps today, with easy PDF and Ajax features - download now http://download.macromedia.com/pub/labs/coldfusion/cf8_beta_whatsnew_052907.pdf Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293022 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

> what you may read as being condescending may actually be a very > sympathetic attempt to help. True... which is why my comments were gentle in nature. (At least that was my intent... :o) I'm most often on the end of the one asking questions instead of being able to provide answers, so I know what it's like to receive answers in the form of questions that assume knowledge that I don't have and, therefore, I can't even begin to understand the significance of the question. Questioning is a very good way to teach, but the answers always have to be in reach of the learner.

Just my opinion, but sometimes it helps to understand the thought process of the person asking the question. If you can understand why they were thinking about a particular solution, you can help them identify where their logic was flawed (it may be well before the actual issue that they were asking about).

RE: CFC in application scope....or else?
The problem is, I didn't see any answer or guidance in the question. When someone has no clue about the broader implications of their question, they can't understand the significance of the response question. It's just obfuscation. Providing some background concerning why the question is "fundamentally flawed" would be more useful than asking questions that he's surely not going to be able to answer. If he could answer the question, he'd probably know the answer to his original question, too.

Why do you think that is? His question was, in my opinion, fundamentally flawed. There is no correct answer for it.

Re: CFC in application scope....or else?
All Singletons are set up in the Application scope regardless of whether you do it yourself or use a dependency injection framework. The benefits of the DI frameworks have more to do with managing dependencies in your model. All that said, I'd recommend looking at ColdSpring for about any size project, since even small projects tend to grow over time and having the foundation in place makes those future changes easier to deal with. The overhead is minimal (since most of it is paid at application startup) and the knowledge will be useful for all of your future projects.

Re: CFC in application scope....or else?
No issue, since by default ColdSpring caches objects in the application scope anyway. As for the original question, yes, there's less value in a dependency injection framework if you don't have dependencies to inject.

What's wrong with putting objects in application scope? As long as it's done right, then what's the issue?
