问题基本上如上所述。在此处的示例中：
http://www.primefaces.org/showcase-labs/ui/mindmap.jsf
如果您单击 NS(s)，您可以单击您选择的子节点之一，例如 ns7.google.com，然后返回 NS(s)，因为连接它们的行仍然存在。
我有 6 个条目，比如 1、2、3、4、5、6。它们都以各种方式链接，在思维导图中以颜色显示。说“1”是根节点。然后 2,3,4,5,6 出现。假设我单击 6 - 重新绘制思维导图以显示 6 的链接，在角落处向上显示 1 以显示它是根。但是，如果我从那里单击除 1 以外的任何节点，链接线都会消失，大多数节点也是如此（我不知道为什么有时它是其中的一些，有时是不同的，有时是一个，有时是全部！）我再也不能倒退了。下面是思维导图 bean 和 html 的代码：
