Refresh business object on parameter change

[#1]

It would be good to have a new option when applying a business object to a form called "Refresh on Parameter change", having logic that will only go back to it's data source if one or more of the parameters change on the form.

The idea behind this is to find a middle ground between always refresh, which refreshes the business object every single time any field with dependants is updated, and a business object that only is populated on form load.

This would increase form load efficiency and stop unnecessary trips back and forth to update business objects that don't require an update.

For example: Currently if the user can select a staff member which will then go and populate more information about that staff member like business title, etc. I either need to load all staff members once off when the form is loaded, or use a parameter to pass in the selected staff member's details and set that business object to always refresh.

The first approach means you need to load a large amount data on form load (slowing down load times), and the second approach means any other fields with dependants causes the query to get the staff member's details to be rerun.

t would require quite an extensive change. Currently the entire Form is refreshed when a field with dependants is changed, or a button is pressed. To set that to change only certain elements depending on changes to ceain variables would be rather complex and definitely prone to both design and functional errors.

Actually correct me if i'm wrong, however the entire form doesn't refresh.

AJAX is used to update those field that have dependants, the other fields without dependants do not refresh.

Which is what makes this solution perfectly reasonable IMO.
