There are 3 types of variables (DATABASE, USER_INPUT, CALCULATED). We have to display them to the user. there is a drop-down of types, selecting one of the options brings up variables that belong to that category. I am trying to do this in a nice clean way, but it's not coming out right. I would appreciate any help or a link.
Another small question... I am displaying a set of drop-down uptions using a Collection from ActionForm. I want there to be a blank row, the value automatically selected when the page first comes up. Do I have to put an empty string into the Collection? Thanks!
