indexOf - 2.0 error... Help! I am desperate?!?

[Tbaseflug]

I have a store - am performing some summary calculations - for the purposes of this calculation - I need to remove duplicate records with same "PackageID" - I found the below - which apparently works in 1.0 but in 2.0 - I get an error on "indexOf" - I am desperate and need to get this in place ASAP... Any help would be GREATLY appreciated and save my day!

   var uniqueIds = store.collect("PackageID");
            store.filterBy(function (r) {
                var id = r.data.PackageID;
                if (uniqueIds.indexOf(id) !== -1) {
                    uniqueIds.remove(id);
                    return true;
                } else {
                    return false;
                }
            });

ExtJS 4.x doesn't inject own methods to standard prototypes anymore, use Ext.Array.indexOf method

OK - That seems to work - I wanted to perform a summary calculation on unique packageIDs only - but still display all inthe grid - so tried the below with the clearFilter at the end - if I take the clearFilter out - the calculation works - but if I leave it in - the calculation picks up all values...

var calculate = function (store, field, field2) {

            var sum = 0, summaryRecord;
            store.each(function (r) {
                //var dup = unique('PackageID', r.get('PackageID'));
                if (r.isSummary) {
                    summaryRecord = r; return;
                }

                var uniqueIds = store.collect("PackageID");
                store.filterBy(function (r) {
                    var id = r.data.PackageID;
                    if (Ext.Array.indexOf(id) !== -1) {
                        uniqueIds.remove(id);
                        return true;
                    } else {
                        return false;
                    }
                });

                sum += r.get(field) * r.get(field2);
            });
            App.storeTarget.clearFilter();
