To elaborate, the goal of "ignoring" the double submit is simply to make the user experience seem as if nothing unusual happened. The result of a double submit should be the same as a single submit.
Towards that goal, both of the strategies you describe here seem reasonable. > -----Original Message----- > From: Richard Feit [mailto:[EMAIL PROTECTED] > Sent: Tuesday, January 04, 2005 3:52 PM > To: Beehive Developers > Subject: Re: svn commit: r124028 - in > incubator/beehive/trunk/netui: > src/compiler/org/apache/beehive/netui/compiler > src/compiler/org/apache/beehive/netui/compiler/genmodel > src/compiler/org/apache/beehive/netui/compiler/grammar > src/compiler/org/apache/beehive/netui > > > I think the feature does allow for the second option, but can you > describe what you mean by "ignoring" the second request? > Currently, I > think that there are a few things that can be done to handle this: > > 1) Go to the original results page, by specifying the path > explicitly in > a @Jpf.Catch for DoubleSubmitException: > > @Jpf.Action( > preventDoubleSubmit=true, > forwards={ > @Jpf.Forward(name="success", path="results.jsp") > }, > catches={ > @Jpf.Catch(type=DoubleSubmitException.class, > path="results.jsp") > } > ) > public Forward placeOrder(OrderForm form) > { > ... > } > > 2) If the results page has request-scoped inputs that were > sent from the > action using @Jpf.ActionOutput annotations, you can use the > 'navigateTo' > attribute, which lets the framework remember the most recent page as > well as the inputs that were passed to it: > > @Jpf.Action( > preventDoubleSubmit=true, > forwards={ > @Jpf.Forward(name="success", path="results.jsp") > }, > catches={ > @Jpf.Catch(type=DoubleSubmitException.class, > navigateTo=Jpf.NavigateTo.currentPage) > } > ) > public Forward placeOrder(OrderForm form) > { > ... > } > > Note that this won't work if the results page is expecting some > other request-(or otherwise-)scoped input that we don't keep track of. > > 3) Go to an error page.
