Now, I would like to have the tree open all the nodes after loading so I added a success function to the ajax attribute. However, I cannot seem to get the open_all() method to work properly. I'm very new to working with jQuery so I'm guessing it's something simple that I'm doing wrong. Firebug isn't showing any errors which rules out the dumb error of mistyped method name.

So, my question. I initialized my tree with some data: $('#tree').jstree({ 'core' : { 'data' : [ 'Simple root node', { 'id' : 'node_2', 'text' : 'Root node with options', 'state' : { 'opened' : true, 'selected' : true }, 'children' : [ { 'text' : 'Child 1' }, 'Child 2'] } ] }); But after some actions, I want to redraw tree with new data. I try to use refresh and redraw methods from API, but it unsuccessfully.
