Can you show the code you're using to get the cart from the event into the page's variables scope? It's possible that there's a structCopy() involved rather than a simple assignment.
The difference is that doing a structCopy() would cause a separate instance of session.cart to be set to the event object and/or the variables scope of your template. If that's the case then the behavior you're seeing makes perfect sense. If this is the case, the byRef nature of structs that you're depending on isn't going to work because you have a discrete COPY of the objects in the event object and variables scope. For some reason this is ringing a bell in the back of my mind as far as MG's functionality and unexpected behaviors. You may be right, I may be crazy. But I just might be the lunatic you're looking for. Give it a try, see what happens. :) Just for shits and giggles, you could also try replacing your function calls with direct references to the relevant variable. I know it breaks encapsulation, but I'm not suggesting you do it for your production code, just remark out your calls to UserSession and CurrentCart and replace them with direct references to the variables. That will eliminate your machinery from the equation and tell you if you have a bug in your code or if there's something deeper going on. You could also try setting session.cart to "" rather than using structDelete(). Replace structKeyExists() with isStruct() and just have session.cart always exist... Man it's been a long time since I've responded to a community support request like this... feels good! Let us know what you find out! J PS - If you really want help with this you might be best off to post the code to the template in question, both controllers, your UserSession and your Cart to something like pastebin.com or nomorepasting.com and send us links to them all so we can see the whole codebase in a format that's familiar and easily readable. Both of those resources provide ColdFusion code support so they will color code highlight things correctly. http://pastebin.com http://www.nomorepasting.com/paste.php On Oct 29, 2012, at 12:26 PM, Jeff P <[email protected]> wrote: > This is in a controller called OrderController Here is the code: > > <cffunction name="processOrder" access="public" returntype="void" > output="false"> > <cfargument name="event" type="any"> > > <!--- get the cart data ---> > <cfset var cart = beans.UserSession.getCurrentCart()> > > <cfif returnCode eq "Y"> > <!--- if payment is successful, ---> > > <!--- clear database tables for the cart ---> > <cfset beans.cartService.removeCartFromDatabase(cart)> > > <!--- clear the cart session ---> > <cfset beans.UserSession.clearCartSession()> > <cfset beans.UserSession.clearCheckout()> > > <!--- delete the credit card temp stuff ---> > <cfset beans.OrderService.deleteCreditCardData(myOrder)> > > <cfset arguments.event.setValue("publicOrderNumber", > myOrder.getPublicOrderNumber())> > <cfset arguments.event.addResult("paymentAccepted")> > > <cfelse> > ..... > </cfif> > > The code to clear the cart session and checkout in the UserSession cfc are: > > <cffunction name="clearCartSession" access="public" output="false"> > <cflock timeout="3" type="exclusive" scope="session"> > <cfset structDelete( session, "cart" )> > </cflock> > </cffunction> > > <cffunction name="clearCheckout" access="public" output="false"> > <cflock timeout="3" type="exclusive" scope="session"> > <cfset structDelete( session, "checkout" )> > </cflock> > </cffunction> > > Thank you Dan. > > On Monday, October 29, 2012 11:02:52 AM UTC-4, Dan Wilson - > [email protected] wrote: > Show the portion of code where you delete the cart after a successful > transaction. > > DW > > On Oct 29, 2012 10:41 AM, "Jeff P" <[email protected]> wrote: > Hey everybody, > > I'm experiencing so strangeness with sessions and am hoping you folks could > shed some light on on what's happening.
