Cannon, Yes! Big plus 1 on this. I discovered it last year. It's really a huge boon to using array based listboxes especially if you've also developed a schema for representing the data objects the listbox displays. Like you say in the past if I wanted to allow a user to do data entry that was going to involve more data each of those had to be in a separate array. And if I wanted to let the user configure which columns of data they wanted to see it just got more complicated.
Now all the data are in the object array, I can easily allow the user to choose the fields they want to display (adding or removing from the listbox) and building the calculations is standardized since there is one, well defined object to refer to. As a final feature any changes can be held in the object array until the user saves or commits them. Useful in some situations.
