問題創建新connectore

我使用gwt連接器爲我的項目，我試圖每次單擊按鈕時創建新的連接器。下面是代碼：問題創建新connectore

public class ERD1 implements EntryPoint { 

public void onModuleLoad() { 

    AbsolutePanel boundaryPanel = new AbsolutePanel(); 
    boundaryPanel.setPixelSize(1000, 1000); 

    final Diagram d = new Diagram(boundaryPanel); 

    Button b = new Button(); 
    b.addClickListener(new ClickListener(){ 

     @Override 
     public void onClick(Widget sender) { 
      SectionDecoration startDecoration = new SectionDecoration 
      (SectionDecoration.DECORATE_ARROW); 
        SectionDecoration endDecoration = new SectionDecoration 
      (SectionDecoration.DECORATE_ARROW); 

      Connector con = new Connector(10, 10, 10, 10, startDecoration, endDecoration); 
      con.showOnDiagram(d); 
     } 

    }); 

    boundaryPanel.add(b, 10, 40); 

    RootPanel.get().add(boundaryPanel); 
} 
}

但是當我點擊按鈕我收到以下錯誤：

請誰能告訴我什麼錯誤。謝謝。

看來你所有的觀點都在同一點。如何嘗試不同的觀點？就像說Connector con = new Connector(10, 15, 29, 100, startDecoration, endDecoration); 什麼的。

我覺得出了什麼問題。

Connector con = new Connector(10, 10, 10, 10, startDecoration, endDecoration);

這裏我有10,10,10,10彼此重疊。這是錯誤的原因。
