sorry, too dark here, pressed wrong button :-)
#2 add to a derived action servlet in the function processValidate:
if ( formInstance instanceof ActionFormEx )
((ActionFormEx) formInstance).populate(mapping,request);
in between the section marked
// Has an input form been specified for this mapping?
..... block of code
and (i.e. add it here).
// Save our error messages and return to the input form if possible
.... block of code
Correct as of beta-1. Now, when the form fails validation, then populate
will be called on the ActionFormEx. With that, you can then fill in any
stuff you require. I wouldn't go stickit it in the session as that stuff can
stay around for ages. plus also the user may invalidate the information with
another click stream anyway so it better to repopulate the object.
