Forward to referer?

[Hans Gerwitz <ja...@phobia.com>]

We want to have a form that appears on many pages, and is hence included
from another file, output by a presentation-layer bean, or whathaveyou.

The problem is that the action the form submits to needs to return to the
view page that contained the form.  This is easy enough (action bean looks
up the HTTP_REFERER header and specifies forwarding to the servlet) but is
the only case where we've had to deviate from looking up a forward name (or
inputForm attribute) via ActionMapping.

My thought: can we specify a "special" forward in action.xml that means
"back to the referring view"?  I haven't dug into the source looking for
this behavior, but I don't think it is there.  If not, can we add it to the
TODO list, Craig?  Have to keep that list healthy :-)

I beg to differ.  mapping.getInputForm() will return the inputForm attribute
of the <action> element in action.xml.  I want a straightforward mechanism
for returning to the *true* referer.  This cannot be known for action.xml
configuration because the action will have been invoked by a form that
exists on many different pages.

In other words, I want a "special" value for the <forward> tag that
evaluates to request.getHeader("Referer") at runtime.

Returning mapping.getInputForm() from your action's perform method will take
you
back to the "referring view".
