At this point we are prompted to hit
Ctrl
+
Shift
, then drag the mouse from the
message component to the field the message will be associated to. After doing so, our

An alternate way of assigning message components to their
corresponding input fields is to set the
for
property to the field's
component id in the
Properties
window.
After executing our application and attempting to submit the form with required
values missing, we will see an error message next to each field with failed validation.
Notice that the field id's are shown in the error message. This default behavior is not
very user friendly, since field id's are not known to the user. We can override this
default behavior by setting the
label
property of each input field; the value of this
property should match each component's label text.
