In my opinion one should always validate inputs coming from a submit even if 
the inputs were disabled. Using tools like firebug, one can easily change 
values of disabled inputs and submit those changed values. Atleast I don't know 
about wicket not submitting disabled inputs, though I would not expect that 
behavior and would not rely on it.

Best regards,
Edwin

Betreff:Component disabled if it contains data

Hello,
I'm using Wicket 6, with Java 1.7.
I'm new to Wicket and I would like to know what is the best way to implement
the following:
-I have a webpage with several input fields bound to a db table, and a
submit button.
- two of the fields can be empty when submitting the changes to the db.
- however, if the fields are filled once, after submitting the page, the
user should not be allowed anymore to change the values(even if leaves and
reenters the page for the same registrations)

Could you please tell me what is the best way to achieve this? 

What I have done so far is:
- on the page load, when the wicket components are added to the page, I
check if the db fields have values, and if they do, then I set the
components to disabled:

Component myComp = new TextField<Integer>("project", new
PropertyModel<Integer>(getModelObject(), "project"));
if (getModelObject().getProject() != null)  
myComp.setEnabled(false);
dtForm.add(myComp ).add(RangeValidator.<Integer>range(0, 999999999));

- also on submit, I check if I have a value in my component and if yes, set
the component to disable:
if (getModelObject().getProject() != null ){
     Component myComp  = get("project");
     if (myComp.isEnabled()){
            myComp.setEnabled(false);
            dtForm.replace(tf);
     }
}

what bothers me is that I need to do all the validation again in the submit
button, every time the submit will be pressed.

Is there a better way?

Thank you
