は、私は、クリックではなく、作品がこのエラーを取得

（画像を更新していない）画像を更新し、その後のパネルでショーのためにイメージをこのコードを使用してしようとしています私はどのように更新できるか知っています。

これは私のコードです：

@Bindable 
class Address { 
    String street, number, city 
    String toString() { "address[street=$street,number=$number,city=$city]" } 
} 



def address = new Address(street: 'Evergreen Terrace', number: '742', city: 'Springfield') 
    def BL = new BorderLayout() 

def swing = new SwingBuilder() 
def swingBuilder = new SwingBuilder() 
swingBuilder.edt { // edt method makes sure UI is build on Event Dispatch Thread. 


    lookAndFeel 'nimbus' // Simple change in look and feel. 

    frame(title: 'Address', size: [1000, 800], 
      show: true, locationRelativeTo: null, 

      defaultCloseOperation: EXIT_ON_CLOSE) { 

     borderLayout(vgap: 5) 

     panel(constraints: BorderLayout.CENTER, 
       border: compoundBorder([emptyBorder(10), titledBorder('Enter your address:')])) { 
      tableLayout { 

       tr { 
        td { 
         label 'Street:' // text property is default, so it is implicit. 
        } 
        td { 
         textField address.street, id: 'streetField', columns: 20 
        } 
       } 
       tr { 
        td { 
         label 'Number:' 
        } 
        td { 
         textField id: 'numberField', columns: 5, text: address.number 
        } 
       } 
       tr { 
        td { 
         label 'City:' 
        } 
        td { 
         textField id: 'cityField', columns: 20, address.city 
        } 
    td { 
         textField id: 'cityField', columns: 20, address.city 
        } 
       } 
      } 


     scrollPane(id:'scroll',preferredSize: [200,200], constraints: context.CENTER) { 



    panel(layout: new FlowLayout()) { 


     label(icon: imageIcon(new URL('pokemon.png'))) 
    } 


     } 





     } 







     panel(constraints: BorderLayout.SOUTH) { 
      button text: 'Save', actionPerformed: { 
       println address 
label.setIcon('pokemon.png'); 
      } 
     } 

     // Binding of textfield's to address object. 
     bean address, 
      street: bind { streetField.text }, 
      number: bind { numberField.text }, 
      city: bind { cityField.text } 
    } 
}

私はこの

@Bindable 
class Address { 
    String street, number, city 
    String toString() { "address[street=$street,number=$number,city=$city]" } 
} 



def address = new Address(street: 'Evergreen Terrace', number: '742', city: 'Springfield') 
    def BL = new BorderLayout() 

def swing = new SwingBuilder() 
def swingBuilder = new SwingBuilder() 
swingBuilder.edt { // edt method makes sure UI is build on Event Dispatch Thread. 


    lookAndFeel 'nimbus' // Simple change in look and feel. 

    frame(title: 'Address', size: [1000, 800], 
      show: true, locationRelativeTo: null, 

      defaultCloseOperation: EXIT_ON_CLOSE) { 

     borderLayout(vgap: 5) 

     panel(constraints: BorderLayout.CENTER, 
       border: compoundBorder([emptyBorder(10), titledBorder('Enter your address:')])) { 
      tableLayout { 

       tr { 
        td { 
         label 'Street:' // text property is default, so it is implicit. 
        } 
        td { 
         textField address.street, id: 'streetField', columns: 20 
        } 
       } 
       tr { 
        td { 
         label 'Number:' 
        } 
        td { 
         textField id: 'numberField', columns: 5, text: address.number 
        } 
       } 
       tr { 
        td { 
         label 'City:' 
        } 
        td { 
         textField id: 'cityField', columns: 20, address.city 
        } 
    td { 
         textField id: 'cityField', columns: 20, address.city 
        } 
       } 
      } 


      scrollPane(id:'scroll',preferredSize: [200,200], constraints: context.CENTER) { 



     panel(layout: new FlowLayout()) { 


    imagelabelx=  label(icon: imageIcon(new URL('pokemon.png'))) 
     } 


      } 





      } 







      panel(constraints: BorderLayout.SOUTH) { 
       button text: 'Save', actionPerformed: { 
        println address 
    imagelabelx.icon= imageIcon(new URL('pokemon2.png')) 
       } 
      } 

      // Binding of textfield's to address object. 
      bean address, 
       street: bind { streetField.text }, 
       number: bind { numberField.text }, 
       city: bind { cityField.text } 
     } 
    }
