The problem is as stated above, essentially. While in the example here:
http://www.primefaces.org/showcase-labs/ui/mindmap.jsf
if you click on NS(s) you can click on one of the childnodes of your choice, say, ns7.google.com, and then go back to NS(s) as the line which joins them remains.
I have 6 entries, say 1,2,3,4,5,6. They are all linked in various ways, which are shown by colour in the mindmap. Say "1" is the rootnode. Then 2,3,4,5,6 show up. Say I click 6 - the mindmap is redrawn to show the links of 6, with 1 up away in the corner to show it's the root. However, if I click on any node other than 1 from there, the linking lines all disappear, as do most of the nodes (I don't know why sometimes it's some of them and sometimes different ones and sometimes one and sometimes all!) and I can no longer go backwards. Below is the code for the mindmap bean and the html:

Any help is greatly appreciated.
I have faced the same problem and eliminated it by simply adding @SessionScoped instead of @RequestScoped.
Now I can select and doubleselect as shown in the example of PF.
