在Plunker工作时,我在实时预览中收到此错误消息:
final ArrayList list1 = new ArrayList();
// This is allowed:
list1.add(new Object());
// But this is not:
list1 = some_other_list;
现在,每当我尝试打开一个新编辑器时,我都会收到此消息。我删除了我的cookie,缓存,尝试在新浏览器中打开相同的plunker,但我一直收到相同的消息。有没有人以前得到过这个? Here's a link to blank plunk. Does it say the same for you in the live preview?
