This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Now how is it that we get the old value of the attribute "a" even if we replace the value of the attribute a?
Is there a way, I could get the new, latest value of "a" the moment it is replaced? This could lead to a potential bug in a production code, not sure why it has to work like this.
