I have realized that I am having a problem with client variables, but I don't know why. I get this message when I try to set a client variable:
Message: The requested scope client has not been enabled. Details: Before client variables can be used, the client state management system must be enabled using the CFAPPLICATION tag. However, I do have the clientmanagement="yes" attribute set in the CFAPPLICATION tag. What am I doing wrong? Is there anything I should be checking on the server?

I'd like the most recently selected item on this dropdown box to be selected whenever I move to a new page view. I can set a variable that holds the last value selected whenever the dropdown is changed, but when I move to a view that does not pass the dropdown box into the form scope, I lose the most recently selected value and it moves to the default value on the next view. I tried placing the MRU value into both session and client variables, and enabling client and session variables in the CFApplication tag, but I just got an error. Also, the most logical place for me to put an assignment for this variable is in a CFC, but I see that Mr. Corfield does not recommend doing this: "It's not that CFCs cannot access scope variables, just that they should not in general (since it breaks encapsulation). The general approach is to create a CFC whose sole job is to 'wrap' the scope access so as to hide it from the rest of the app." http://lists.topica.com/lists/mach-ii-coldfusion/read/message.html?mid=81031 3532&sort=d&start=2193 So where/how can I create a variable that persists this information?
