When I changed the value of the duplicate object of which the attribute is array type, then the original object will be contaminated. I thought if there are some bugs in method $.widget.extend().

I give an example as following:

$.widget("x.grid", {
        options: {
    columns:[]
          ……
   }, 
        _create: function(){

    this.options.columns[0] = {……}; // ?

    this.options.columns[1] = {……};

    this.options.columns[2] = {……};

    this.options.columns[3] = {……};

   }

after doing this above, the original options.columns will be contaminated.
