RouterLinkActive for children routes all false

Question

I have the following routes for children:

{ path: '', component: LoginSingupComponent,
  children: [
    { path: 'login', component: LoginComponent },
    { path: 'singup', component: SingupComponent },
  ]
},

Switching to /loginor /singupworking fine (correct component loaded).

This is an excerpt from LoginSingupComponent

<nav md-tab-nav-bar class="mb-1">
  <a md-tab-link routerLink="/login" routerLinkActive [routerLinkActiveOptions]="{exact: true}" #rla="routerLinkActive" [active]="rla.isActive">Entrar {{rla.isActive}}</a>
  <a md-tab-link routerLink="/singup" routerLinkActive [routerLinkActiveOptions]="{exact: true}" #rla="routerLinkActive" [active]="rla.isActive">Criar uma conta{{rla.isActive}}</a>
</nav>

When /logineverything is on rla.isActive == false, when on /singupeverythingrla.isActive == true

I tried without exact: true

Answer 1

Found a problem.

This was because I exported as rounterLinkActive with the same variable name, which causes this behavior.

<a md-tab-link routerLink="/auth/login" routerLinkActive [active]="rlal.isActive" #rlal="routerLinkActive">Entrar {{rlal.isActive}}</a>
<a md-tab-link routerLink="/auth/singup" routerLinkActive [active]="rlas.isActive" #rlas="routerLinkActive">Criar uma conta{{rlas.isActive}}</a>

Solves the problem.

Try it like this:

<nav md-tab-nav-bar class="mb-1">
    <a md-tab-link [routerLink]="['/']" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">Home</a>
    <a md-tab-link [routerLink]="['/login']" routerLinkActive="active">Login</a>
    <a md-tab-link [routerLink]="['/singup']" routerLinkActive="active">Signup</a>
</nav>
