Error and Missing Template handler Not working

[cfwheelsnubee]

Good morning all.

I have inherited a very old CFWHEELS app (over 10 years old).

I am trying to get the Error and Missing Template handlers  to work and have tried everything and they just don't fire off.

Here is my onerror code

<cffunction name="onError" returntype="void" access="public" output="true">

    <cfargument name="exception" type="any" required="true">

    <cfargument name="eventName" type="any" required="true">

    <cfscript>

        var loc = {};

        // in case the error was caused by a timeout we have to add extra time for error handling.

        // we have to check if onErrorRequestTimeout exists since errors can be triggered before the application.wheels struct has been created.

        loc.requestTimeout = 70;

        if (StructKeyExists(application, "wheels") && StructKeyExists(application.wheels, "onErrorRequestTimeout"))

        {

            loc.requestTimeout = application.wheels.onErrorRequestTimeout;

        }

        $setting(requestTimeout=loc.requestTimeout);

        loc.lockName = "reloadLock" & application.applicationName;

        loc.rv = $simpleLock(name=loc.lockName, execute="$runOnError", executeArgs=arguments, type="readOnly", timeout=180);

    </cfscript>

    <cfoutput>

        #loc.rv#

    </cfoutput>

</cffunction>

<cffunction name="$runOnError" returntype="string" access="public" output="false">

    <cfargument name="exception" type="any" required="true">

    <cfargument name="eventName" type="any" required="true">

    <cfscript>

        var loc = {};

        if (StructKeyExists(application, "wheels") && StructKeyExists(application.wheels, "initialized"))

        {

            if (application.wheels.sendEmailOnError && Len(application.wheels.errorEmailAddress))

            {

                loc.mailArgs = {};

                $args(name="sendEmail", args=loc.mailArgs);

                if (StructKeyExists(application.wheels, "errorEmailServer") && Len(application.wheels.errorEmailServer))

                {

                    loc.mailArgs.server = application.wheels.errorEmailServer;

                }

                loc.mailArgs.from = application.wheels.errorEmailAddress;

                loc.mailArgs.to = application.wheels.errorEmailAddress;

                loc.mailArgs.subject = application.wheels.errorEmailSubject;

                loc.mailArgs.type = "html";

                loc.mailArgs.tagContent = $includeAndReturnOutput($template="wheels/events/onerror/cfmlerror.cfm", exception=arguments.exception);

                StructDelete(loc.mailArgs, "layouts", false);

                StructDelete(loc.mailArgs, "detectMultiPart", false);

                try

                {

                    $mail(argumentCollection=loc.mailArgs);

                }

                catch (any e) {}

            }

            if (application.wheels.showErrorInformation)

            {

                if (StructKeyExists(arguments.exception, "rootCause") && Left(arguments.exception.rootCause.type, 6) == "Wheels")

                {

                    loc.wheelsError = arguments.exception.rootCause;

                }

                else if (StructKeyExists(arguments.exception, "cause") && StructKeyExists(arguments.exception.cause, "rootCause") && Left(arguments.exception.cause.rootCause.type, 6) == "Wheels")

                {

                    loc.wheelsError = arguments.exception.cause.rootCause;

                }

                if (StructKeyExists(loc, "wheelsError"))

                {

                    loc.rv = $includeAndReturnOutput($template="wheels/styles/header.cfm");

                    loc.rv &= $includeAndReturnOutput($template="wheels/events/onerror/wheelserror.cfm", wheelsError=loc.wheelsError);

                    loc.rv &= $includeAndReturnOutput($template="wheels/styles/footer.cfm");

                }

                else

                {

                    $throw(object=arguments.exception);

                }

            }

            else

            {

                $header(statusCode=500, statusText="Internal Server Error");

                loc.rv = $includeAndReturnOutput($template="#application.wheels.eventPath#/onerror.cfm", exception=arguments.exception, eventName=arguments.eventName);

            }

        }

        else

        {

            $throw(object=arguments.exception);

        }

    </cfscript>

    <cfreturn loc.rv>

</cffunction>

And they are called in wheels/functions

<cfset this.name = Hash(GetDirectoryFromPath(GetBaseTemplatePath()))>

<cfset this.mappings["/wheelsMapping"] = GetDirectoryFromPath(GetBaseTemplatePath()) & "wheels">

<cfset this.sessionManagement = true>

<cfif StructKeyExists(server, "railo") OR StructKeyExists(server, "lucee")>

    <cfinclude template="../config/app.cfm">

    <cfinclude template="controller/appfunctions.cfm">

    <cfinclude template="global/appfunctions.cfm">

    <cfinclude template="events/onapplicationend.cfm">

    <cfinclude template="events/onapplicationstart.cfm">

    <cfinclude template="events/onerror.cfm">

    <cfinclude template="events/onmissingtemplate.cfm">

    <cfinclude template="events/onsessionend.cfm">

    <cfinclude template="events/onsessionstart.cfm">

    <cfinclude template="events/onrequest.cfm">

    <cfinclude template="events/onrequestend.cfm">

    <cfinclude template="events/onrequeststart.cfm">

<cfelse>

    <cfinclude template="config/app.cfm">

    <cfinclude template="wheels/controller/appfunctions.cfm">

    <cfinclude template="wheels/global/appfunctions.cfm">

    <cfinclude template="wheels/events/onapplicationend.cfm">

    <cfinclude template="wheels/events/onapplicationstart.cfm">

    <cfinclude template="wheels/events/onerror.cfm">

    <cfinclude template="wheels/events/onmissingtemplate.cfm">

    <cfinclude template="wheels/events/onsessionend.cfm">

    <cfinclude template="wheels/events/onsessionstart.cfm">

    <cfinclude template="wheels/events/onrequest.cfm">

    <cfinclude template="wheels/events/onrequestend.cfm">

    <cfinclude template="wheels/events/onrequeststart.cfm">

</cfif>

Any suggestions?

When you say they don't work, what *do* you get when you do cfthrow() ?

What environment mode are you in? The main error handlers (which send emails + display the "nice" message) will only kick off in production; development/design should just output the native error stacktrace.

If you're getting a white screen, it might be a server configuration issue (like secure error template handling).

So - which version of wheels + what CF engine?

I just created an error and was actually able to verify that the onerror.cfm is being called. The message shows in the console but not on the page. Now I need to get the missing template file to show. FYI - it doesn't show in production either.

[Tom King]

Can you clarify about "showing in console"? Are you calling it via JS?

It might be if you're on a old version of wheels that you need to bufferoutput = true in your application settings.
Lucee recently updated this (5.3) not sure about ACF. In config/app.cfm add this.bufferOutput = true; and reload - that may well help

Sorry. In the developer tools. I am getting closer. Got it to work in Chrome. It may be cached in IE. Will try the bufferoutput. Thanks
