Re: TActionList and datamodules

Not at all.  Your TAction can simiply call  a public method on your

logic to a 3rd layer and just do your data layer on he datamodule.  But
either way you can keep the real logic away from your prensentation
layer.


Mmmmh... looks like my target is blurry :-)

Ok, let's see if I can explain better what I'm thinking of.

I usually have this kind of structure for database applications:

1) GUI
2) Logical datamodules
3) Database datamodule
4) Reporting

This means that each section has its own module set.
This makes things much easier when it comes to mantain the applications.

Now, you're suggesting that part of what composes the logical datamodules be placed on the GUI, from my point of view - and that
breaks the separation imho.

Cheers,
