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?

Your format is wrong, since the total count is inside of each array element. Unfurtunatelly you will need to change your format. You can try something like:

// inside your reader (gets the totalCount of the first array element)
totalProperty: 'Weather[0].totalCount'

But it really isn't the right choice, since it does not make sense to have each array element with the same count, don't you agree?
