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.
