Angular无法使用其他数量的子代重新附加ActivatedRouteSnapshot [英] Angular Cannot reattach ActivatedRouteSnapshot with a different number of children

问题描述

这是我在一个本机脚本角度项目中的路由:

Here is my routing in a nativescript-angular project:

const routes: Routes = [

    {
        path: "",
        redirectTo: "/tabs/default",
        pathMatch: "full"
    },
    {
        path: "tabs",
        loadChildren: "~/app/modules/tabs/tabs.module#TabsModule"
    },
    {
        path: "login",
        loadChildren: "~/app/modules/login/login.module#LoginModule"
    },
    {
        path: "register",
        loadChildren: "~/app/modules/register/register.module#RegisterModule"
    }

];

@NgModule({
    imports: [NativeScriptRouterModule.forRoot(routes, {
        preloadingStrategy: PreloadAllModules
    })],
    exports: [NativeScriptRouterModule]
})

导致错误的情况:首先，应用程序以选项卡路由开始，然后我进入登录页面，之后我进行注册，然后再次进入选项卡页面(并清除历史记录).之后，如果我再次进入登录页面并返回上一个页面(标签"页面)，则会发生错误.

The scenario which leads to the error: First the app starts with tabs route, then I go to the login page, after that I go to register and then again I go to tabs page (and clean the history). After that if I go to login page again and get back to previous one (tabs page), the error occurs.

错误:

有什么主意吗?

推荐答案

您尝试过传递relativeTo附加功能吗?奇怪的是，这对我有用，我不知道如何以及为什么.

Did you try passing the relativeTo extras? Weirdly this worked for me and I can't figure out how and why.

this.routerExtension.back({relativeTo: this.activatedRoute});

喜欢这个.
