Can transport data parameter be a function ?

[Richard]

With this data source configuration .read() does not seem to be passing &group= and &subgroup= assignments to the server.  

var spaceSeasonDS =

new kendo.data.DataSource({

    transport: {

        read: {

            url: window.stpURL + "/SpaceAttribute",

            dataType: 'xml',

            data: {

                action: 'getSeasons',

                group: function(){

                    return spaceGroup.value()

                },

                subgroup: function(){

                    return spaceSubgroup.value()

                }

            },

            cache: false,

            complete: onReadComplete_Season

        }

    },

    schema: {

        type: "xml",

        data: "/TABLE/SEASONS",

        model: {

            fields: {

                item: "item/text()"

            }

        }

    },

    error: raiseXmlDsErrorWindow

});

Should 

data: {

    action: 'getSeasons',

    group: function(){

        return spaceGroup.value()

    },

    subgroup: function(){

        return spaceSubgroup.value()

    }

},

be this instead ?

data: function() {

return {

        action: 'getSeasons',

        group: spaceGroup.value(),

        subgroup: spaceSubgroup.value()

}},

Hi Richard,

Yes, the group and subgroup parameters should not be a functions. Instead you could use one of the following approaches:

data: {
    foo: parseInt($("#test").val())
}

data: function () {
    return {
        foo: parseInt($("#test").val())
    }
}
