Struts: empty ActionForm after failed validation on a MultiPartRequest
----------------------------------------------------------------------

                 Key: STR-2921
                 URL: http://issues.apache.org/struts/browse/STR-2921
             Project: Struts 1
          Issue Type: Bug
            Reporter: Pedro Boado
            Priority: Trivial


Working with Struts 1.1 I got into a strange situation: when you post a 
"multipart/form-data" with "" elements and the validate() method of the 
ActionForm fails, you are forwarded to the InputMapping specified into the 
"struts-config.xml" file, while Struts logs the message " Rolling Back 
Multipart Request ".

Struts documentation says that Rollback sets to null ActionForm's FormFile 
objects . But, my ActionForm arrives totally empty to the forwarded Action, as 
is a reset() operation were performed.

What did I do? I made a clone() to the ActionForm when I checked if there were 
errors in the validate() method, I attached the clone into the request object 
and retrieved it while processing the InputMapping's Action, and then I filled 
up the current ActionForm.

P.D. : Sorry for my bad English
