Pass down router to child components via context -

i trying pass down router via context, can call navigateto on child react.component.

purpose:
need navigate away login when have successful login.
strategy:
1. passdown router childe login component.
2. when login call navigateto('/startpage') on router passed down.

i have on page/component contains run:

router.run(routes, function (handler) {     react.render(<handler/>, document.body); }); 

the following context setup:

getchildcontext() {     return {         router: router     }; } 

and childcontexttypes:

childcontexttypes = {     router: react.proptypes.object.isrequired }; 

and child itself:

contexttypes = {     router: react.proptypes.object.isrequired }; 

the context setup works fine if using "router: react.proptypes.string.isrequired". note strings, when using object get:

but when try use object errors:

warning: failed context types: invalid context 'router' of type 'object' supplied 'navitemlink', expected 'function'. check render method of

and:

uncaught typeerror: this.context.router.isactive not function

any welcoming?

the solution worked me create function on parent , pass down context.

parent:

contexttypes = {         router: react.proptypes.func.isrequired     }; 

and on child components:

childcontexttypes = {         router: react.proptypes.func.isrequired     };
