Hello,

My tree  is loaded from JSON
How can I open the root node after that my root children loaded ?

If I put directly into my JSON code  "state : { open: true}" option, the node is opened but children are not drawed.
I must close and reopen the node to see something.



--- my tree ---

    tree = new Mif.Tree({
                    container: $('mytree'),
                    grid: true,
                    sortable: false,
