When we arrive on technique editor, the is not fully loaded at once. It can be problematic with a lot of technique, we should add a loading effect before the tree is fully loaded.
Maybe use something like :

$(selector)
.bind('before.jstree', function(e, data) {
    // invoked before jstree starts loading
})
.bind('loaded.jstree', function(e, data) {
    // invoked after jstree has loaded
    $(this).jstree("open_node", $(nodes[i]));
})
