錯誤的ColdFusion

返回一個隱含的結構時，基礎錯誤的ColdFusion

我運行一個CF10u10盒與Apache作爲我的本地機器上的Web服務器。我是cfscript的粉絲，並且儘可能地使用新的隱式struct {}聲明Vs structNew（）。

守則

文件是一個組件和一個CFM。

componentFile.cfc

<cfcomponent output="false"> 

    <cffunction name="blahExplicit" returntype="Struct"> 
     <cfset var name = 'ColdFusion'/> 
     <cfset var ret = structNew()/> 
     <cftry> 
       <cfreturn {success: true, data: name}/> 
      <cfcatch type="any"> 
       <cfset ret.success = false /> 
       <cfset ret.data = cfcatch /> 
       <cfreturn ret/> 
      </cfcatch> 
     </cftry> 
    </cffunction> 

    <cffunction name="blahImplicit" returntype="Struct"> 
     <cfset var name = 'ColdFusion'/> 
     <cftry> 
       <cfreturn {success: true, data: name}/> 
      <cfcatch type="any"> 
       <cfreturn {success: false, data: cfcatch.detail}/> 
      </cfcatch> 
     </cftry> 
    </cffunction> 

    <cffunction name="script_blahExplicit" returntype="Struct"> 
     <cfscript> 
      var name = 'ColdFusion'; 
      var ret = structNew(); 
      try{ 
       return {success: true, data: name}; 
      } catch(Any err){ 
        ret.success = false; 
        ret.data = err.detail; 
        return ret; 
      } 
     </cfscript> 
    </cffunction> 

    <cffunction name="script_blahImplicit" returntype="Struct"> 
     <cfscript> 
      var name = 'ColdFusion'; 
      try{ 
      return {success: true, data: name}; 
      } catch(Any err){ 
       return {success: false, data: err.detail}; 
      } 
     </cfscript> 
    </cffunction> 
</cfcomponent>

cfcatchErr.cfm

<cfset cObj = createObject("component","componentFile")/> 
<cfdump var="#cObj.blahExplicit()#" label="blah Explicit"/> 
<cfdump var="#cObj.script_blahExplicit()#" label="blah Explicit With Script"/> 
<cfdump var="#cObj.script_blahImplicit()#" label="blah Implicit With Script"/> 
<cfdump var="#cObj.blahImplicit()#" label="blah Implicit"/>

的問題

解析器拋出一個錯誤，說明詳細在cfcatch未定義用於blahImplicit （）方法。但對於其餘的方法

凡爲在blahExplicit（）的代碼，script_blahExplicit（），script_blahImplicit（）只是正常工作都不錯。

問題

這究竟是爲什麼？爲什麼即使不運行代碼，CF也會拋出錯誤？它在解析時本身拋出錯誤。我使用ACF Builder，發現一旦達到嘗試，控制跳到捕獲。

這是一個已知的問題或新的東西？爲什麼返回一個隱含的結構體的問題？

注意：我喜歡Railo過，但只允許在這種情況下談論CF 10。我提交了bug to Adobe。

你請可以包括實際的錯誤信息，而不是僅僅描述它。請包括堆棧跟蹤的最初部分，請。 –

@AdamCameron做到了主人:) – Sanjeev

好消息是我可以在CF9上覆制這個，所以可以使用它。感謝真正好的repro例子，順便說一句。 –

這絕對是一個CF中的錯誤，非常好，你記錄它（3605215）。

最方便的變通，我可以想出是使用中介變量，如：

<cffunction name="blahImplicit" returntype="Struct"> 
    <cfset var name = 'ColdFusion'/> 
    <cftry> 
      <cfreturn {success= true, data= name}> 
     <cfcatch type="any"> 
     <cfset var ret = {success= false, data= cfcatch.detail}><!--- this will prevent the error ---> 
      <cfreturn ret> 
     </cfcatch> 
    </cftry> 
</cffunction>
