Sorry about the delay, I was hiding from the computer!
The first question is simply this.... what does makeEventBean()
actually do? From your comments, I would expect that it probably
creates a bean that exists for the life of the request and attempts
to "see" if any of the variables that have been passed through in
the event match the arguments of those for the bean that we are
creating.... is that correct ?
Exactly!
Or are you saying that because the DAO is essentially supposed to
be a singleton, even if I do add it to the separate controllers,
they are all in fact, referencing the same object ? (Am I grasping
this correctly here? Or am I way off?)
Again, looks like you've got it. The default behavior of ColdSpring
is to treat all the defined beans as singletons, so yes any object
that calls getBean('yourDAO') will receive a reference to the same
object.
As far as AutoWiring goes, Sean's already answered that one.
I hope that helps!

Hi Chris,
Thanks for the reply.... very informative, however I do (as
always!) have another question (or two!).

Why would we put the DAO's in the controller ? I would expect that
several controllers will require access to the same DAOs, isn't
there a better place to put them that will allow access from all
controllers ? Or are you saying that because the DAO is
essentially supposed to be a singleton, even if I do add it to the
separate controllers, they are all in fact, referencing the same
object ? (Am I grasping this correctly here? Or am I way off?)
Finally, with regards to the AutoWire stuff, are you saying that by
adding that setStaffDAO to my controller, that Coldspring will
automatically try to determine how to pass this DAO to my
controller when the controller is first created ? Is there
anything special that I have to do to get this autowire controller
working? From what I can gather, it's in the current BER / Alpha
release....
Sorry for my confusion - and thanks again for bearing with me on
this one :D
Cheers,
Callum
