dojo - dijit.Tree refresh and focusNode -

i found out how refresh tree , works fine. want focus on specific node , says _itemnodesmap undefined.

here have:

    require([      "dojo/_base/window", "dojo/data/itemfilewritestore",      "dijit/tree/foreststoremodel", "dijit/tree",      "dojo/domready!"     ], function(win, ifrs, foreststoremodel, tree){     dojo.extend(tree, {        reload: function (data, path) {                     this.dndcontroller.selectnone();  this.model.store.clearonclose = true;  this.model.store.close();   this._itemnodesmap = {};  this.rootnode.state = "unchecked";  this.model.root.children = null;  this.rootnode.destroyrecursive();       var _data  = {identifier: "id", label: "label", items: data};  var _store = new ifrs({data:_data});  var _treemodel = new foreststoremodel({         store: _store,             rootid:"root",             rootlabel:"things",             childrenattr:["children"]   });     this.model.constructor(_treemodel);     this.postmixinproperties();     this._load();     path.unshift("root");     this.set('path',path);     }}); 

for focussing tried add following , call after setting path:

   scroll : function(path){    var itemnode = this._itemnodesmap[path[path.length-1]];    this.focusnode(itemnode[0]);    } 

but _itemnodesmap undefined. why? tree displayed, path set , except works. great help. thanks!

i believe setting path deferred process, assuming path variable in scroll function has taken consideration, use following focus on tree item (node) in then function:

var item = mytree.path[path.length-1]; var nodes = mytree.getnodesbyitem(item); if (nodes && nodes.length > 0 && nodes[0]) {     nodes[0].domnode.scrollintoview(true); }
