jsf - Primefaces add treenode in database -

-

i'm using primefaces 5.0 , create treenode draggable (as example detailed in http://www.primefaces.org/showcase/ui/data/tree/dragdrop.xhtml).

i update tree node in database don't understand it.

my actual solution first remove database treenode , after add new treenode built user. every item in treenode custom object, getrowkey() method can build new tree index.

is best way?

thanks.
