Extending a TypeScript class with multiple generic parameters

Question

i try to extend a React Component Class with generic Parameters but I cannot get it working. According to the TypeScript Docs and this TypeScript Class Generic Parameter Constraints, and this extending a class with a generic T I ended up in the following (not working) code:

Base Class:

class BaseView<P, S> extends React.Component<P, S> {
    public constructor(props: P, state: S) {
        super(props, state);
    }
}

const mapStateToProps = store => {
    console.log('store', store);
    return {
        store
    };
};

function mapDispatchToProps(dispatch) {
    console.log('dispatch', dispatch);
    return {
    };
}

export default connect(mapStateToProps, mapDispatchToProps)((BaseView as any));

export function subclass<P, S>(c): BaseView<P, S> {
    return c;
}

The class which extends the Base Class:

I tried different ways, using the factory like this:

export class Documents extends subclass(BaseView)<DocumentsProperties, DocumentsState> { 
// this leads into ""BaseView<{}, {}>" is no constructor function type

or without using the factory:

export class Documents extends BaseView<DocumentsProperties, DocumentsState> { 
// no base constructor has the specified number of type arguments

I also tried out several other ways but i feel like i was programming for the first time of my life....I cannot get it running for multiple Parameters. What am I missing here?
