The RouteParams encounter a problem because it is unable to resolve all parameters

I'm encountering an issue with the RC3 router. The error message I am receiving is: Can't resolve all parameters for RouteParams: (?). Below is my code:

//route.ts

import {provideRouter, RouterConfig} from '@angular/router';
import {HomeComponent} from './components/home.component';
import {ActionsComponent} from './components/actions.component';
import {TasksComponent} from './components/tasks.component';
import {DetailsComponent} from './components/details.component';
import {ActionFormComponent} from './forms/action-form.component';
import {TaskFormComponent} from './forms/task-form.component';
import {ActionViewFormComponent} from './forms/action-view-form.component';
import {TaskViewFormComponent} from './forms/task-view-form.component';


export const appRoutes: RouterConfig = [

    {path:'', component:HomeComponent},

    {path:'actions',component:ActionsComponent},
    {path:'actions/:id',component:ActionFormComponent},
    {path:'actions/new', component:ActionFormComponent},
    {path:'actionview',component:ActionViewFormComponent},

    {path:'tasks',component:TasksComponent},
    {path:'tasks/:id',component:TaskFormComponent},
    {path:'tasks/new', component:TaskFormComponent},
    {path:'taskview',component:TaskViewFormComponent}
];

export const APP_ROUTER_PROVIDER = provideRouter(appRoutes);

//boot.ts

 import {bootstrap} from '@angular/platform-browser-dynamic';
 import {HTTP_PROVIDERS, Http} from '@angular/http';
 import {provideRouter} from '@angular/router';

import {APP_ROUTER_PROVIDER} from './routes';

import {AppComponent} from './app.component';

bootstrap(AppComponent, [APP_ROUTER_PROVIDER, HTTP_PROVIDERS]);

//appComponent

import {Component} from '@angular/core';
import {PostService} from './services/post.service';
import { Observer } from 'rxjs/Observer';
import {Input} from '@angular/core';
import {HTTP_PROVIDERS, Jsonp} from '@angular/http';
import {Http, Headers, BaseRequestOptions, RequestOptions} from '@angular/http';
import {NavBarComponent} from './components/navbar.component';
import {OnInit, Output} from '@angular/core';

import { provideRouter, RouterConfig, ROUTER_DIRECTIVES, ActivatedRoute, Router } from '@angular/router';
import { RouterLink, RouteParams, ROUTER_PROVIDERS } from '@angular/router-deprecated';

@Component({
    selector: 'my-app',
    template: `
   <navbar></navbar>

    <div class="container">
        <router-outlet></router-outlet>
    </div>
    `,
    directives:[NavBarComponent, ROUTER_DIRECTIVES, RouterLink],
    providers:[PostService, HTTP_PROVIDERS, ROUTER_DIRECTIVES]

On my navbar template, I am using the following router link structures:

<li><a [routerLink]= "['actions/']" routerLinkActive="active">Actions</a></li>
         <li><a [routerLink]="['tasks/']" routerLinkActive="active">Tasks</a></li>

Answer №1

When using Angular rc3, it is necessary to define routes like this:

{

path: '/dashboard',

name: 'Dashboard',

component: dashboardComponent,

useAsDefault: true }

In rc4, the name property is no longer required. However, in rc3, it is mandatory to provide the name property for routes.

I trust that this solution resolves your issue. :)
