I have a simple page the has 2 parts...
Part 1) Information at the top about a contact that the user is viewing.
Part 2) A form where a user can edit the information of a transaction
that relates to the contact.
When the user enters a invalid entry for a number field (in this
example xaction.listPrice), everything works perfectly in Part 2 of
the page (a fieldError is given and the form refilled). However, Part
1 is null since the parameterInterceptor doesn't call my action class.
How do I "refill" the Contact object information when this happens?
Or is my implementation of the Struts framework incorrect?
Many thanks for any assistance/guidance!
