If it works for you then by all means go with it. From my own perspective, though, one based on my own experiences, I've found it best to adhere to tried and true OO principles. There are always exceptions of course and doing something in a prescribed manner without questioning the logic of doing it that way is dangerous in its own right. However, discounting the wisdom of sound principles is equally dangerous IMO.
One of the things I really love about developing an application is the iterative process of going back, over and over again, over what I've implemented and how I've implemented it and doing constant code reviews. I am my harshest critic :) Jeff On Sun, Nov 28, 2010 at 12:36 PM, Rein Petersen <rein.peter...@gmail.com>wrote: > Thanks Jeff, > > You're right - the way you have described is the way I should do it.
