ContentBox is a complete package, and it would be to make sure that the latest ColdBox is used and reduces support requests.
Now having said that, there is NO reason why you can’t just extract just the modules and drop them into an existing ColdBox application, just be aware that the minimum ColdBox version will change as fixes are made to ColdBox.
Andrew, I’ve been struggling to install into existing coldbox app that uses a global CF mapping. Then I tried it in reverse - I first installed contentbox then wrapped it with my parent app and it went well because I used the embedded packaged.
I prefer the modular setup so I can use global mappings, but I have to continue trying to figure out how to make it work. My latest issue is described here: Google Groups
