Validator lost data when go back to form
Hi,
I'am using validator to validate data on client side and server side.
It works fine, but when I validate on server side when there are errors detected I go back to the html but without user data (the form is reseted).
Have you got any idea ?
Thanks in advance,
Jean-Marie.

RE: Validator lost data when go back to form
Posted by Martin Gainty <mg...@hotmail.com>.
It *appears* you are redirecting the user in which case you are losing all
of the users session Data
You may want to define the ActionMapping to forward the request and ensure
redirect=false
Here is an explanation of the use of redirect vs forward
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg21820.html
Here is doc on implementation details for the use of redirect for
ActionForward
http://www.ingrid.org/jajakarta/struts/struts1.0/en/target/documentation/api/org/apache/struts/action/ActionForward.html#ActionForward(java.lang.String,%20boolean)
Anyone else?
