I use this documentation for save and restore treetable state:
In my situation it doesn't work , maybe because I reload treetable from server ?
1) I load treetable from server (nodes closed)
2) I open parent nodes buy clicks
3) I save the treetable state
4) I reload treetable from server (node closed)
5) I restore treetable last state
When I look in firebug, the treetable data saved with open nodes in local storage are ok but the nodes are always closed in view
