This problem is all about the session scope and its complex relationship to the application name and the cfid and cftoken cookies. You would be having the same problem with a simple integer in the session scope under the same conditions. It is just a matter of figuring out what those conditions are. What do you have defined in the 'this' scope in the application.cfc in the cart folder? How does that relate to an tag in the application.cfm site root? ~| Want to reach the ColdFusion community with something they want?

Re: cfinvoke newb question
the reson the id's are different is becasue the link i sent. it had the cfid in it.. any how the stuff that does the cart is all from chapter 22 of cfwack 8-1 the application.cfc in the folder cart is pretty simple just change the name or commented it out? the application.cfm is at the site root. and dosnt have any thing to do with the cart... basically the way i think it should go if you are on this page and click add item http://63.144.103.199/products/index.cfm?n1Id=11&n2Id=81&n3Id=295 it shuld fire off component rittalxpress.cart.ShoppingCart cfc. which is called by #SESSION.myshoppingcart# or some thing... the http://63.144.103.199/rittalxpress/cart/LX_right1.cfm is included on any of those xpress pages and just shows you a count and such of what you have http://63.144.103.199/rittalxpress/cart/StoreCart.cfm shows the actual results... here at home i see http://63.144.103.199/products/index.cfm?n1Id=11&n2Id=81&n3Id=295 throwing an error. but i can add items... see result count seperatly here: http://63.144.103.199/rittalxpress/cart/LX_right1.cfm which is same include throwing error.. and see items in cart here: http://63.144.103.199/rittalxpress/cart/StoreCart.cfm i am flustered and am gonna grab a beer and play prototype for a bit. maybe if you get a sec and can point me in the right direction i will hask it out in the mornning... ~| Want to reach the ColdFusion community with something they want?

They will not share data with each other. Somehow or the other the way your application is structured you are creating different sessions, possible because of different applications, in different parts of the application. To solve this we would need to see the directory structure of your application, where do you have Applicaiton.cfm and|or Applicaiton.cfc files, and what is in those files to define the application environments. ~| Want to reach the ColdFusion community with something they want?

There is a change one has to make when one starts working with components and putting them into persistent memory. It is not something ColdFusion developers had to worry about in the days where every request resulted in the CFM code being interpreted. With that just-in-time interpretation, any change in the CFM source file would take immediate effect the very next time the file was requested. When one starts creating components and persisting them in memory, one has to think about the difference between the code that is in the source file and the code that is already in memory and that a new request for the object in memory is not going to require a call to the source file unless it does not exist in memory or something tells it to reinitialize the object from the source file. ~| Want to reach the ColdFusion community with something they want?

Another strange one. I think what is required here is that the directory that contains the file being called: D:\webserver\rittal-corp.com\www\rittalxpress\cart\ Make sure that this directory is covered by an Application.cfc or Application.cfm file that defines the same name as the rest of the application code. ~| Want to reach the ColdFusion community with something they want?

Paul Ihrig wrote: > if i am cfincluding the page from another page out side the directory > with the app.cfc and other cfc > it craps out on me.. My first thought is that when you include it from outside the main directory with the Application.cfc, it causes the code to run outside of the define "Application' and thus has no access to the shared memory. This is a prime example of why accession data outside of a component with code like #session.myShoppingCart# is considered a bad OOP practice. The best practice advice to to always pass the required data into the component as arguments, don't require the component to be aware of the environment outside of itself. There is a complex relationship between the name of an Application as defined by the "name: property of the tag OR the 'this.applicationName" property of an Application.cfc file. Any code that does not run under the same name does not share the same Application or Session memory states. When one starts using components, it is common to put them outside the web root where the code does not run under the defined application name and thus does not share the memory. ~| Want to reach the ColdFusion community with something they want?
