问题 2 Questions - In CF8 in the application.cfm I cold set a global variable like so <cfset DSN = "dej6_42"> I am now trying to adjust to the Application.cfc in CF10/Lucee and can not figure out how to set this same variable. Here is my current Application.cfc <cfcomponent output="false"> <cfset This.name = "My Application"> <cfset This.clientmanagement="True"> <cfset This.loginstorage="Session"> <cfset This.sessionmanagement="True"> <cfset This.sessiontimeout="#createtimespan(0,0,10,0)#"> <cfset

Why don't I get a recursive infinite loop when throwing an error in the onError function?

阅读更多关于 Why don't I get a recursive infinite loop when throwing an error in the onError function?

问题 In my coldfusion Application.cfc file, I define an onError function. In certain situations, I explicitly throw an exception using a cfthrow tag - e.g. <cfthrow object="#myException#"> . My question is, why doesn't this create an infinite loop? Or at least cause another call to the onError function? (Instead, it just dumps the error to the screen. Which is the functionality I want, actually :) - but I'm still confused about why this happens.) 回答1: This is expected and documented behavior: If

问题 How to translate <cferror type="EXCEPTION" template="ErrorTemplate.cfm"> to an onError() function for Application.cfc? Notice that cferror create a var error struct for the template. Is there a quick and easy way to create the same error struct? How to pass that into ErrorTemplate.cfm using <cfinclude> ? I know onRequest() shares the variable scope with the target page, but does onError share variables scope too? If not, what shall I do? Stick it to the Form scope? Thank you 回答1: According to

问题 Hi I'm very new with ColdFusion 10 especially with Application.cfc. It is very confusing. I created Application.cfc and inside this cfc I created the following: My questions are: 1. Why do I get session error? (see my codes below) 2. What should I put in sessionEnd function?  <CFCOMPONENT displayname="Application" output="true"> <cfset THIS.Name = "MyTestApp" /> <cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,60,0) /> <cfset THIS.SessionManagement = true />

问题 Is there a way to explicitly reference the THIS scope defined in Application.cfc? Say I have an Application.cfc like this: component { this.name="MyApplication" .. I know that from any page in the site, you can access this.name this way... <cfoutput>#this.name#</cfoutput> ...but if you are in another component, how would you reach the Application.cfc's "this" scope? Is it possible without handing the var off? Adobe documentation says that you can reference the "THIS" scope by using the

ColdFusion: Are there any use cases where an Application.cfm is preferable to an Application.cfc

阅读更多关于 ColdFusion: Are there any use cases where an Application.cfm is preferable to an Application.cfc

问题 I'm in the process of upgrading a large legacy ColdFusion application that heavily utilizes Application.cfm template files instead of the newer Application.cfc files. It seems that Application.cfc offer a cleaner more efficient solution to everything that a Application.cfm file can do. An Application.cfm runs every line sequentially for every request, so it would recreate application variables on every subsequent new page query. (Can cause performance hit if many application variables loaded)

问题 How do I create Search Engine Safe URLs in Fusebox 5.1 noxml?

This question already has answers here : Closed 7 years ago . Possible Duplicate: restart application without restarting server? How do I reset a Coldfusion Application / application.cfc without resetting the Coldfusion Server instance? If I remember right, there are a few tricks out there such as creating a reinit function within application.cfc or renaming the file. A couple of steps: First, make sure all your application initialization logic is contained inside the OnApplicationStart method of your CFC. If it has nested calls, that is fine - just so long as you can re-initialize your
