gwt-ext 布局问题

悬赏园豆：20 [待解决问题]

我用gwt-ext 在panel中加入了三个radio button，前两个button后边分别对应一个textarea，第三个后边没有，我的代码如下：

Panel myPanel = new Panel();
myPanel.setLayout(new FitLayout());
myPanel.setBorder(false);
myPanel.setPaddings(5);

FieldSet detailsFS = new FieldSet("Radio Test");
detailsFS.setCollapsible(false);
detailsFS.setHeight(500);

Radio radio1 = new Radio("Radio 1", "Radio");
radio1.setHeight(45);
Radio radio2 = new Radio("Radio 2", "Radio");
radio2.setHeight(45);
Radio radio3 = new Radio("Radio 3", "Radio");
radio3.setHeight(45);

TextArea textArea1 = new TextArea();
textArea1.setHeight(40);
TextArea textArea2 = new TextArea();
textArea2.setHeight(40);

FieldSet first=new FieldSet();
first.setBorder(false);
first.setHeight(400);
first.add(radio1,new AnchorLayoutData("99%"));
first.add(radio2,new AnchorLayoutData("99%"));
first.add(radio3,new AnchorLayoutData("99%"));

FieldSet second=new FieldSet();
second.setBorder(false);
second.add(textArea1,new AnchorLayoutData("99%"));
second.add(textArea2,new AnchorLayoutData("99%"));

Panel tempPanel=new Panel();
tempPanel.setLayout(new ColumnLayout());
tempPanel.add(first,new ColumnLayoutData(.3));
tempPanel.add(second,new ColumnLayoutData(.7));
