If you looks at the mx.controls.Alert class, you can only give the
show() method a listener object, and that object must implement a
click() method. You can't specify which method the Alert may call, so
I'm stuck giving it an object that has one click(). If this object
happens to be the MXML, then I can't use it for different Alerts,
because each one will only call click().
So now I have to decide where the proper place for click() should be.
I don't want to use groupdetails.mxml, for the reason stated above (I
also have buttons that deactivate groups, and do other things, all
backed by Alerts). I don't know if it should go into the
DeleteGroupCommand. I supposed I could add a click() method to this
command, that kicks off an event that runs the same command, but that
seems messy. It also somewhat ties my command to my view, since the
Alert is just a UI technicality. This leaves the
GroupDetailsViewHelper, but again, using this class for broadcasting a
command event might not be right.
Thoughts?
