我正在Netbeans中編寫一個可視化應用程序,並遇到了需要一個對話框。我決定複製Netbeans自動提供的AboutBox代碼段,只是發現這兩個代碼都會引發錯誤!簡單的JDialog導致堆棧溢出

我似乎無法追捕錯誤的來源,雖然兩者都是關閉對話框時引起的。

爲了簡單起見,因爲我相信這兩個錯誤是相關的,這裏是我的Dialog。爲簡潔起見,我省略了initComponents()和main(從未調用過)方法,但defaultCloseOperation是DISPOSE_ON_CLOSE

運行時出現堆棧溢出,我將在下面發佈。

public class AddRecipe extends javax.swing.JDialog { 

/** Creates new form AddRecipe */ 
public AddRecipe(java.awt.Frame parent, boolean modal) { 
    super(parent, modal); 
    initComponents(); 
} 

AddRecipe(java.awt.Frame parent) { 
    super(parent); 
    initComponents(); 

} 

private void cancelButtonMouseClicked(java.awt.event.MouseEvent evt) { 
    dispose(); 
} 


// Variables declaration - do not modify 
private javax.swing.JLabel Serves; 
private javax.swing.JButton acceptButton; 
private javax.swing.JButton cancelButton; 
private javax.swing.JLabel jLabel1; 
private javax.swing.JLabel jLabel2; 
private javax.swing.JList jList1; 
private javax.swing.JScrollPane jScrollPane1; 
private javax.swing.JScrollPane jScrollPane2; 
private javax.swing.JTextArea jTextArea1; 
private javax.swing.JTextField nameTextField; 
private javax.swing.JTextField servesTextField; 
private javax.swing.JTextField timeTextField; 
// End of variables declaration 

}

(堆棧跟蹤重複幾百次)。

爲了完整起見,下面是調用Dialog的函數。再一次,這個代碼是建立在默認的Netbeans行爲模型之上的,(即使AboutBox Netbeans提供的原因是java.lang.reflect.InvocationTargetException)。

private void newRecipeItemActionPerformed(java.awt.event.ActionEvent evt) { 
    if (addRecipe == null) { 
     JFrame mainFrame = RecipesApp.getApplication().getMainFrame(); 
     addRecipe = new AddRecipe(mainFrame); 
     addRecipe.setLocationRelativeTo(mainFrame); 
    } 
    RecipesApp.getApplication().show(addRecipe); 
} 
+6

爲什麼堆棧跟蹤中有XML事物?你有沒有試圖將這個簡單的JDialog作爲一個單獨的小項目運行(不是大項目的一部分)? – 2011-01-25 00:15:28

正如Ashton K在評論中提到的,這個問題可以通過轉移到JDK的Oracle版本來解決。所以這個問題是至少運行他的特定版本的OpenJDK的問題。
