Question

I have a full tree with multiple items and multiple levels, the tree is build with an ajax call and uses lazy nodes

So now i want to add the function so my tree can load and select and item if i give the full path, but before i can select the item i need to make sure that the item is loaded with lazy loading so i can access it.

I found the function .loadKeypath(), so for testing i retrieved the full path to my node with

node.getKeyPath();

so the path is /12/16/17/18

So i figured out i should put this code after the ajax data was loaded in

onPostInit: function(isReloading, isError){
                $("#tree").dynatree("getTree").loadKeyPath("/12/16/17/18", function(node, status){
                    if(status == "loaded") {
                        // 'node' is a parent that was just traversed.
                        // If we call expand() here, then all nodes will be expanded
                        // as we go
                        node.expand();
                    }else if(status == "ok") {
                        // 'node' is the end node of our path.
                        // If we call activate() or makeVisible() here, then the
                        // whole branch will be exoanded now
                        node.activate();
                    }else if(status == "notfound") {
                        var seg = arguments[2],
                            isEndNode = arguments[3];
                    }
                });
            }

But now i get this warning in the console:

Node not found: 12 jquery.dynatree.js:49

Adn this is the full log

So how can i load a node what tis nested in other nodes

Answer 1

This is an answer for future reference

After some debugging and help from the dynatree developers, we came up with a solution, if you want to load up a key path use an string as key and not an integer.

instead of

 "icon": false,
        "checkbox": false,
        "title": "xxxxxxxx",
        "key": 23,
        "type": "child"

use

 "icon": false,
        "checkbox": false,
        "title": "xxxxxxxx",
        "key": "23",
        "type": "child"

That way the loadkeypath function will pickup the correct path!
