I took an intro Java class and trying to put things to work in CF. Previously I had placed all instance variables in the variables scope, so basically at the top of the CFC I would declare variables.instance.varname for each instance variable...and then I decided to change it to this.variables.instance.varname... now I'm confused, whats the difference?
