JFace dailog button事件中刷新透视图异常 Trying to execute the disabled command org.eclipse.ui.window.closePerspective

报错的代码为

Display.getDefault().syncExec(new Runnable() {
public void run() {
localpmtsStreamViewsAction.refreshPerspective(localviewId,
localw);
}
});

super.buttonPressed(buttonId);

}

抛异常：

这个问题的解决办法：只需要改变代码的顺序即可

protected void buttonPressed(int buttonId) {

super.buttonPressed(buttonId);//这一行代码放到这里

Display.getDefault().syncExec(new Runnable() {
public void run() {
localpmtsStreamViewsAction.refreshPerspective(localviewId,
localw);
}
});

}
