paging in grid extjs
===

i want to use the paging toolbar but have one problem. I don't make the service so i need to work with the json i have. The problem is that the format of the json is different then the tutorials.

    {
    "Weather": [{
        "totalCount": 2962,
        some data
               },{
        "totalCount": 2962,
        some data
               }]
    }

but in the tutorials i saw it should be

    {
    "totalCount": 2962,
    "Weather": [{
        some data
               },{
        some data
               }]
    }

Is there a way i could use the format i have? I tried to do this:

    proxy: {
          type: 'ajax',
	  url: detailURL,
           reader: {
             	type: 'json',
             	root: 'Weather',
                totalProperty: 'Weather.totalCount'
         }
       },

that didn't worked. Suggestions?
