Not sure which pattern "this pattern" refers to here ;-) More than a few have been mentioned. > > One question. What is the origin of this pattern?

If you need to know that here are some options: - Hire somebody whos job it is to tell you you know all the available patterns until you feel confident - just slit your wrists now =8^0 Seriously, I look at it this way. You approach problems with your experience, intellect and your toolbox. Patterns are part of that toolbox. The list of available patterns to you or me, is the list of patterns I recognize and can implement successfully. I may know about other patterns but not have the experience with them to use them yet. I will never have learned all the patterns, mostly because there is no "master list" to consult. Part of my job though is to learn those things that apply to my work so I can further build my toolbox. And then you move on to the next problem.
