deselect_node.jstree event is not getting triggered

[Violet Valiev]

Hi there,

I need to save some data before the user navigates to a new node, hence, I need to bind to the deselect_node.jstree event. My tree is initialized as follows (I omitted some code that does not seem relevant):

var plugins = ["themes", "ui", "contextmenu", "types", "unique"];
var core_config = {
    "multiple": false,
    "check_callback": true,
    'data': function (node, cb) {
        cb(SessionService.getModelAsJson());
    }
}

treeDiv = $(sourceDiv);
treeDiv
    .jstree({
        'plugins': plugins,
        'types': types_def,
        'contextmenu': contextmenu_def,
        'core': core_config
    })
    .bind('loaded.jstree', function (event, data) {
        data.instance.select_node(selectNodeId);
        defer.resolve();
    })
    .bind("deselect_node.jstree", function (event, data) {
        $log.log("deselect_node.jstree");
    })

    .bind("select_node.jstree", function (event, data) {
       /* cbMap['onNodeSelect'](
            SessionService.getSelectedNode(), data.node);*/
    });

Hi,

What happens if you deselect a node programatically?

  var instance $treeContainer.jstree(true);
  instance.select_node(yourNodeId);
  instance.deselect_node(yourNodeId);

select_node and deselect_node are more of internal events, you would be better off with changed.jstree - the event data obejct provides a lot of information.
If you still want to use this code - that is fine - just listen for both deselect_node and deselect_all, as selecting another node will not trigger a deselect_node event for each selected node, but a single deselect_all event which will have information about all deselected nodes.

Best regards,
Ivan
