Maybe I should have stated I have tried something like this. I have data entry TextFields for:
SalePrice DiscountAmount then add another for: DiscountPercentage When I enter an amount into DiscountAmount I need DiscountPercentage to get calculated and update on the form. And it should also work the other way around - enter DiscountPercentage and DiscountAmount gets updated. But DiscountPercentage does not have a setter in my model - just a getter (it's calculated for viewing only and does not get persisted anywhere). So I get errors when Wicket attempts to update the model. And if I enter an an amount in DiscountPercentage and attempt to update the value for DiscountAmount then I can't update this either since I don't want to persist the form until all the other fields are entered. I am using the same form for creating a new record and editing an existing one, so when doing a new record I don't have mandatory fields filled when I'm entering the Discount stuff.
