Re: Cannot access session variables in a cfc

Were you using relative paths to the CFCs. That could become hairy if you move things around. I'll generally define a CFC path variable in the application.cfm then use that everywhere.

Re: Cannot access session variables in a cfc
You will need to pass your session variables as a parameter in order to use them in the CFC, this is best practices anyways. The difficulty is that there a lot of cfc calls and some of them are in bind expressions so the chance of making errors is high. That's why I am so anxious to find one that doesn't make me change a lot of programming.

Re: Cannot access session variables in a cfc
Hmm, that's odd as I use that setup on numerous sites and I never have to map the applicationproxy. I am currently using it on both ACF 10 and 11, but I started using this around 8 or 9 and haven't changed it for new version. I don't believe that you could use the root.(dot) notation in 8 or 9, which if I remember correctly, predicated the use of the proxy. Every site is also housed in completely different directories, nowhere near the cfusion/wwwroot directory, so I am not sure why it is didn't work for you as well. Anyway, thanks for the additional info regarding cutting out the proxy step.

Re: Cannot access session variables in a cfc
Thanx. That's what I think I will do for the time being. It is hard for me to come up with all the symptoms that we started seeing on the cfc's now and I don't think I could do justice to any explanation of those issues. It seemed to me that it was all quite normal stuff. All pages and cfc's were in the same doc root. And I have had issues with cfc locations on my test system because it gets confused with localhost and virtual directories, so getting the cfc's into a separate folder had a certain appeal. I'm planning to do a big refresh on the app over the summer and this is going to be addressed then. In the meantime, I have my fingers crossed than an application scoped variable will get us through.

While I agree it isn't a good practice to make use of scope variables in a CFC, try adding an Application.cfc in the root physical directory of your CFCs and use the same application name and session and app timeouts.

It seems that they work for around a day and then can no longer be found. I initialize them in my application.cfm to a value and I can still cfdump them in a regular web page, but the cfc fails with the error Element XXX is undefined in SESSION. Is this normal behaviour? If it is, then what is the alternative method of passing a variable into the cfc (other than making it a parameter when calling)? ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:360030 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
RE: Cannot access session variables in a cfc
try adding an Application.cfc in the root physical directory I don't that that will work. It would still be a separate application pool, and I think you need the CFID and CFTOKEN cookies to have session vars.

Re: Cannot access session variables in a cfc
You could also extend the main application.cfc. You can't do this directly if the cfc's are in a sub-directory though. If that is the case, you could use a proxy, I do this all the time. Here would be the structure. root - Application.cfc - ApplicationProxy.cfc (extends Application) - cfc-folder - - Application.cfc (extends ApplicationProxy) - - myCFC.cfc You will probably want to also call super.onApplicationStart() from within the cfc folder Application.cfc's onApplicationStart() method. The same would hold true for onSessionStart(), you would want to call super.OnSessionStart(). This ensures that all the main application and session vars get initialized properly.

Re: Cannot access session variables in a cfc
John, There are some pretty significant advancements to CFCs since CF 7, especially around scoping. You definitely want to look at the difference up the version chain.

It is hard for me to come up with all the symptoms that we started seeing on the cfc's now and I don't think I could do justice to any explanation of those issues. It seemed to me that it was all quite normal stuff. All pages and cfc's were in the same doc root. And I have had issues with cfc locations on my test system because it gets confused with localhost and virtual directories, so getting the cfc's into a separate folder had a certain appeal. I'm planning to do a big refresh on the app over the summer and this is going to be addressed then. In the meantime, I have my fingers crossed than an application scoped variable will get us through. Thanx again. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:360034 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
