LoDashStatic.filter isn't working

[pocesar]

I have this class method: (using Typescript 1.0.1 and latest lodash type definitions)

        getSelected(type: string, one:boolean):void;
        getSelected(type: string, one:boolean):IDataItem[];
        getSelected(type, one:boolean = true):IDataItem {
            if (one) {
                return _.reduce<IDataItem, IDataItem>(sections[type], (current: IDataItem, p: IDataItem) => {
                    return p.selected === true ? p : current;
                }, void 0);
            } else {
                return _.filter<IDataItem>(sections[type], (p: IDataItem):boolean => {
                    return p.selected === true && p.enabled === true;
                });
            }
        }

it's giving me:

planner.ts(801,24): error TS2012: Cannot convert 'IDataItem[]' to 'IDataItem':
        Type 'IDataItem[]' is missing property 'name' from type 'IDataItem'.

for _.reduce, it works properly. sections[type] are IDataItem[]

not a problem with lodash, but from my lack of understanding typescript overloads
