Visibility status of open sublevels

[felixzapata]

hi, If I have some sublevels on a row and I open each of them, if I close the most top parent, when I open again the sublevels doesn not maintain their visibility status.

I mean (I open "Level 1", "sub level 1" and open "sublevel 1"):

1. Level 1
   1.1 sub level 1
   1.1.1 sub level 1
   1.2 sub level 2

When I close "Level 1" and I open again the result is:

1. Level 1
   1.1 sub level 1
   1.2 sub level 2

the level 1.1.1 should show open, because it´s was open when close the parent

This behaviour it is doing ok on jQuery.treetable
