Flex語法錯誤

Question

我在嘗試訪問model.connection屬性時出現以下代碼中的語法錯誤1202（訪問包模型中的未定義屬性連接）。我看不出爲什麼會出現這種情況，任何人都可以看到我可能忽略的某些內容？

Model.as

package valueObjects 
{ 
import flash.data.SQLConnection; 

import mx.collections.ArrayCollection; 

public class Model 
{ 
    public var connection:SQLConnection; 
    public var albums:ArrayCollection = new ArrayCollection(); 
    public var albumItems:ArrayCollection = new ArrayCollection(); 
    public var selectedAlbum:Number = 0; 
    public var selectedItem:Number = 0; 

    public function Model() 
    { 
    } 
} 

}

而且在我的默認MXML文件的實際代碼時，init（）調用初始化

 import model.ModelLocator; 

     import mx.core.mx_internal; 

     import valueObjects.Model; 

     protected var sqlConnection:SQLConnection; 
     private var model:Model = new Model(); 

     protected function init():void 
     { 
      createDb(); 
      navigator.firstViewData = model; 
     } 

     protected function createDb():void 
     { 
      sqlConnection = new SQLConnection(); 
      sqlConnection.open(File.applicationStorageDirectory.resolvePath("Oxford.db")); 
      var stmt:SQLStatement = new SQLStatement(); 
      stmt.sqlConnection = sqlConnection; 
      stmt.text = 
       "CREATE TABLE IF NOT EXISTS albumItems (" + 
       "id INTEGER PRIMARY KEY AUTOINCREMENT, " + 
       "album INTEGER, " + 
       "name STRING, " + 
       "dateAdded DATE)"; 
      stmt.execute(); 

      model.connection = sqlConnection; 
     }

這裏的問題是，你有一個包和一個名爲'model'的變量。當您嘗試訪問名爲model的變量時，它認爲您指的是包。如果你改正這個命名衝突，你會發現這個問題已經修復。
