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);
}
});
}
