>Not sure if I'm putting this correctly, but I found myself putting a number of properties on a form that contained patient demographic data that was passed into the form. Would it be better to create a form array (object, collection?) that contained all the different properties for the patient? How would I do that? I know how to creat a form array, but is there a different/better way to have a collection of items that will need to be in scope for the entire form?

Could you create a class that contains only the data that represents patient info? Then you could pass this class to the form or any other object and it would only be one parameter. Then, in the Init of the form store it to a form property. If you really felt inspired, you could code in methods to retrieve, update and the save changes.
