Delete Validation -- with Vector displayed
Hello Everyone,
I have a 'Delete' button in my JSP (a submit button). As the button is
submitted, a method gets called (from the Action class) to do the following:
1. checks if the field is NOT used by entities 2. Based on 1, either the
field gets deleted, or the field does not get deleted and a Vector of
entities using the field is returned.
How can I validate/ display a message to the user in case the field is used
and cannot be deleted? The error message should also include the entities
using the field (which is a Vector, or a string).
Thank you,
Mona

Return an ActionError with a message parameterized to include the names of
the entities, then on the JSP, render that errors collection.
