    Default i find a way

    i find a way


    i find

    Jsonreader.java
    Code:
    public ListLoadResult read(C loadConfig, Object data)
    TreeStore.java
    Code:
    protected void onLoad(TreeLoadEvent le) {
       .....
       for (M model : (List<M>) le.data)
       .....
    }
    le.data is ListLoadResult not List<M> lead the error.

    so,i extend the JsonReader.java


    Code:
     public ArrayList<ModelData> read(C loadConfig, Object data)

    Demo has realize

    1)rails providing json data
    2)tree node dynamic loading
