;-) (Frank, any particular reason for not liking dispatching actions?)
It's off-topic for this discussion I think, so I'll give you a quick answer (as quick as I'm capable of at least!), and if you'd like to discuss it more, feel free to eMail me or start a new thread somewhere...
First, I should point out that I don't not use DispatchActions at all, but I tend not to 95% of the time. Also, I have no solid *technical* reason not to use them. It just doesn't quite *feel* right to me...
First, I prefer looking at 10 different classes with 10 lines of code a piece than one with 100 lines of code. My brain has an easier time following the smaller classes (sometimes at the price of it being harder to see the whole). I find that it makes it easier for others to grasp code when they are being exposed to it for the first time too (I suspect this is just a psychological thing... they feel more confident in their ability to comprehend 10 lines of code than 100, something like that).
In addition, I think it makes working in teams a little easier... this tends to be true any time you make things more granular. You can dole out tasks in a more fine-grained way.
I also think it makes unit testing easier, or at least more finely focused.
I think there is less chance of breaking something inadvertently when you have to make a change with a regular Action than a DispatchAction (although I admit I have no evidence to support this one at all!)
Also, I prefer to think of a web application as a collection of loose, independent and atomic services that can be requested individually to form a coherent whole (even if those services are tightly related). Having each individual function broken out in its own class jives with that perception a little better.
Lastly, I don't like the idea that I can't really guarantee what is going to be executed. What I mean is that if I have a mapping that uses a particular regular Action, I know for sure precisely what is going to be executed if that URL is requested. With a DispathAction though, I have no such guarantee because it's based on a parameter that could be fudged. Leaves a little more room for hackery IMO.
I don't mean to try and convince anyone by the way... I already know I'm in the minority :)
Oh geez, I really *can't* give a brief answer, can I?!?
