I am trying to move our app to 4.0 and have run into some errors. Mostly compatibility issues which I have been able to resolve except:
Error building: interceptor-SES -> Requested instance not found: ‘sessionStorage@cbstorages’ The instance could not be located in any declared scan location(s) (pms-es.models) or full path location with constructor arguments: {controller={[(Component=coldbox.system.web.Controller)]},properties={{}}}
I have installed cbstorages in my modules folder and other code seems to be using it correctly. Any ideas? Thanks!
Basically using the default routes.cfm except for a http or https param based on the environment…
// Allow unique URL or combination of URLs, we recommend both enabled
setUniqueURLS(false);
// Auto reload configuration, true in dev makes sense to reload the routes on every request
//setAutoReload(false);
// Sets automatic route extension detection and places the extension in the rc.format variable
// setExtensionDetection(true);
// The valid extensions this interceptor will detect
// setValidExtensions('xml,json,jsont,rss,html,htm');
// If enabled, the interceptor will throw a 406 exception that an invalid format was detected or just ignore it
// setThrowOnInvalidExtension(true);
// Base URL
// ** Note: IIS URL Rewrite can be used to removed index.cfm from the URL
if( len(getSetting(‘AppMapping’) ) lte 1){
setBaseURL("#getSetting(‘urlPrefix’)#://#cgi.HTTP_HOST#/index.cfm");
}
else{
setBaseURL("#getSetting(‘urlPrefix’)#://#cgi.HTTP_HOST#/#getSetting(‘AppMapping’)#/index.cfm");
}
// Your Application Routes
addRoute(pattern=":handler/:action?");
/** Developers can modify the CGI.PATH_INFO value in advance of the SES

My reason for these are so I don’t have to use getInstance(‘xxx@xxx’) throughout… unless there is some easier way to do to have universal variables throughout the app?
Unfortunately, you are trying to execute this, when modules are not loaded yet. The chicken and egg problem.
This is because the application helper gets injected in handlers, interceptors and the like. I would not encourage the use of many global variables due to the fact that it is hard to debug.
However, you can delay construction of dependencies by using providers, so you don’t have to use the try/catch:
OK thanks… I will try that. My reason for the helper is because we have a lot of session variables in a legacy app which we are going to be converting to ColdBox and it seemed to make sense to have a shortened variable to call for session variables. Are there any other ways you think of which may be better?
Luis is correct. Now that we have modularized ColdBox, application startup is a sticky process. Depending on the order that all the modules are loaded up, it’s possible that other parts of the framework might try to access them before they exist. We could rearrange the startup order to fix one scenario, but it would simply create another issue elsewhere since something has to get loaded first.
Perhaps we should document a list of all the things that load before modules do to help people avoid these scenarios. I’ll also point out the module service has a method called “isModuleActive()” that allows you to check and see if a given module has been loaded prior to using it. Of course, I think Luis’s provider suggestion is still better, since checking “isModuleActive()” might just lead to your variables not existing unexpectedly.
I actually noticed this and put in this ticket so we could discuss options. This ticket is about autowiring a modules models into an interceptor. Since the applicationHelper is run on interceptor creation, your issue is pretty much the same thing: https://ortussolutions.atlassian.net/browse/COLDBOX-417
Oops. Sorry about that. I should have tested that code in a live RCD. You need to pull wirebox and logbox in via your controller. It should be:
public void function configure(){
var wirebox=controller.getWirebox();
var prc = event.getCollection(private=true);
prc.sessionStore = wirebox.getInstance(‘SessionStorage@cbstorages’);
prc.clientStore = wirebox.getInstance(‘ClientStorage@cbstorages’);
prc.msg = wirebox.getInstance(‘messagebox@cbmessagebox’);
//Asking logbox for the root logger
prc.logger = controller.getLogBox().getRootLogger();
prc.helpDeskNo = controller.getSetting(“helpDeskNo”);
}
That’s because there’s no getInstance() method in the request context or it’s decorator. This is due to the fact that it doesn’t extend the frameworksupertype. I don’t know if there’s a really good reason why it doesn’t-- Luis would need to address that. You have the controller available to you. Ask it for wirebox, and proceed from there.
> If I put the code into the configure function in system RequestContextDecorator.cfc file the error does not happen.
Well, that’s most likely because your configure method isn’t calling super.configure() which means it never gets run, and therefore “doesn’t error”.
Look at the source code! It’s instance.controller, not controller (which will search the variables scope). The getController() method is just a convenience method in the decorator to get instance.controller for you.
I have an app running 4.3 and all runs well (i’ll update this to 5.x but been busy updating the other apps) but periodically the app starts showing an error that the requested instance sessionStorage@cbstoreages can not be located in any declared scan locations. I reinit the app and all is well for some period of time. I don’t have any fancy scan locations.
Any ideas?
Example code in main.cfc where the error is ocurring:
public void function onRequestStart(event)
{
//set the session for client
if (getInstance(‘sessionStorage@cbstorages’).getVar(‘clientid’) lt 1) // error is being thrown here
{
do some stuff
}
