Subject: [Stripes-users] Preserving unbound values on save
I have a situation where I have a JSP form and it is populated with values from
an object pulled from a database.
Below is some sample code off the top of my head. It might not compile. The
names have been changed to protect the innocent.
The problem I'm having is that the Customer object contains a lot more fields
than are displayed on the page for the user to edit. And when the user saves
the page, anything not explicitly named on the page and bound to the customer
object in the action bean gets set to null.
I know that I can add hidden tags on the page as a way to deal with this, but
there's a lot of extra un-bound fields in the Customer object, and I really
don't want to add a bunch of hidden tags. Plus, this exposes the data in those
fields to any user who views the source on the html page.
The Customer object was designed to mirror the database model, but the user
view into that model isn't 100% of the data.
This has to be a common problem. Ideally, I'd like to have something where
unbound members of the customer object are just left with their original
values. Short of maintaining two separate Customer objects, one for the screen
and one for the database and juggling data back and forth between the two, is
there a way to deal with this situation?
public class EditCustomerAction extends BaseAction {
private Long customerId;
private Customer customer;
@DefaultHandler
public Resolution view() {
if (customerId != null) {
customer = CustomerClient.getInstance().retrieveCustomer(customerId);
}
return new ForwardResolution(EDIT_CUSTOMER_JSP);
}
public Resolution save() {
if (customer != null && customerId != null) {
CustomerClient.getInstance().updateCustomer(customerId, customer);
}
return new RedirectResolution(NEXT_JSP);
}
public Resolution cancel() {
return new RedirectResolution(PREV_JSP);
}
public Long getCustomerId() { return customerId; }
public void setCustomerId(Long customerId) { this.customerId = customerId; }
public Customer getCustomer() { return customer; }
public void setCustomer(Customer customer) { this.customer = customer; }
}
