问题是如上所述，基本上。虽然在这里例如：点击一个孩子的孩子，线条消失 - Primefaces 3.4 mindmap
http://www.primefaces.org/showcase-labs/ui/mindmap.jsf
如果你点击NS（）你可以点击你所选择的的childNodes之一，比方说，ns7.google.com，然后回去NS（ s）作为连接它们的线仍然存在。
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。说我点击6 - 重绘的思维导图显示6的链接，在角落里有1个显示它的根。然而，如果我从那里点击1以外的任何节点，连接线都会消失，大部分节点也是如此（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，有时甚至是全部）！我不能再倒退了。下面是对思维导图bean和HTML代码：
