Re: [flexcoders] Re: Methods in ModelLocator - or not?

[Samúel Jónasson]

Thank you for your responses. I had thought about utility classes - just wasn't sure how that fitted within cairngorm.  I think both methods make sense but using utility classes probably fits cairngorm better than having methods inside the model. But, then again - do what works - even if it isn't cairngorm by the book. Sammi jamesdustinmercer wrote: I don't see anything wrong with the approach you are taking. I do the same thing (that's probably why I don't see anything wrong with it :). I think of it this way, if the methods you need to add directly correspond with the data, and they are ambiguous of any commands or other business logic, then the model locator is not a bad place for it. I also add methods to encapsulate the adding, removing, and updating of items (when I need to validate the data coming or getting updated, standard setter getter type stuff...) But as someone else said, utility classes are also good. You just have to feel out when you need to do either one. A utility class could be good in this situation because it will save you from writing repeating lookup code for each different collection in the ModelLocator.
