java - 单击子节点的子节点，线条消失 - Primefaces 3.4 思维导图

Question

问题本质上如上所述。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，例如 1、2、3、4、5、6。它们都以各种方式链接，并在思维导图中以颜色显示。假设“1”是根节点。然后 2,3,4,5,6 出现。假设我单击 6 - 思维导图将重新绘制以显示 6 的链接，其中 1 位于角落以显示它是根。但是，如果我单击除 1 之外的任何节点，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是其中一些节点，有时是不同的节点，有时是一个节点，有时是全部节点!)我不能再走回头路了。下面是思维导图 bean 和 html 的代码:

Answer 1

我也遇到过同样的问题，并通过简单地添加 @SessionScoped 而不是 @RequestScoped 来消除它。

现在我可以选择并双击，如 PF 示例所示。
