Topic: Automatically select a node onload /oncomplete

Is there anyway to automatically select a node once the tree has initially loaded?

sorta like:

tree = new Mif.Tree({
         ......
}).addEvent('onComplete',function(){
        this.select(node);
});

Or I am currently using expand to to make the node visible to the end user, is there anyway of expanding this so that I can use this to automatically set the node as selected.

options: {
     autoSelect: true
}
expandto: {
expandTo: function(node){
     if(this.autoSelect == true) {
          node.toggleSelected();
     }


    if (!node) return this;
        var path = [];
        while( !node.isRoot() && !(this.forest && node.getParent().isRoot()) ){
            node=node.getParent();
            if(!node) break;
            path.unshift(node);
        };
        path.each(function(el){
            el.toggle(true)
        });
        return this;
    },
}

I know this code is totally wrong but just trying to get an idea where to start...

Re: Automatically select a node onload /oncomplete

onComplete -> load or loadChildren
yes you can select node using expandTo function:

Tree.implement({
    expandTo: function(node){
        if (!node) return this;
        var path = [];
        while( !node.isRoot() && !(this.forest && node.getParent().isRoot()) ){
            node=node.getParent();
            if(!node) break;
            path.unshift(node);
        };
        path.each(function(el){
            el.toggle(true)
        });
        this.select(node);//select
        return this;
    }
})

where is problem?
