unable to get serverside pagination to work with colvis library

snj

I am using datatables 2.2.3 with colvis 1.1.1. Everything works fine with clientside. Basically column filtering, search, sorting all of them work with clientside data.
When I turn on serverside pagination (set bServerSide=true) I see that columns, order search data are being sent as "object" when I remove the reference of colvis library I see that columns as an array of each columns in datatable. I see this data in firebug. Basically iam trying to view the json data being sent to server.

Looking forward for some help.

Without colvis:

{"draw{"draw":2,
"columns":[
{"data":"fistcolumnname","name":"firstcolumnname","searchable":true,"orderabale":true,

    },
    "data":"secondcolumnname","name":"secondcolumnname","searchable":true,"orderabale":true,
]

}

With colvis:

{
"columns":[
{object:object,object:object,object:object},
{object:object,object:object,object:object},
{object:object,object:object,object:object},

]

}
":2, "columns}
