Hallo,

ich habe folgenden Aufbau

src\Resources\app\administration\src\module\kk-qanda\index.js

import './page/kk-qanda-list';
import './page/kk-qanda-detail';
import './page/kk-qanda-create';

//...

  routes: {
    list: {
      component: 'kk-qanda-list',
      path: 'list'
    },
    detail: {
      component: 'kk-qanda-detail',
      path: 'detail/:id',
      meta: {
        parentPath: 'kk.qanda.list'
      }
    },
    create: {
      component: 'kk-qanda-create',
      path: 'create',
      meta: {
        parentPath: 'kk.qanda.list'
      }
    }
  },

//...

src\Resources\app\administration\src\module\kk-qanda\page\kk-qanda-create\index.js

const { Component } = Shopware;

Component.extend('kk-qanda-create', 'kk-qanda-detail', {
    methods: {
        getQanda() {
            this.qanda = this.repository.create(Shopware.Context.api);
        },

        onClickSave() {
            this.isLoading = true;

            this.repository
                .save(this.qanda, Shopware.Context.api)
                .then(() => {

import template from './kk-qanda-detail.html.twig';

const { Component, Mixin } = Shopware;

src\Resources\app\administration\src\module\kk-qanda\page\kk-qanda-detail\kk-qanda-detail.html.twig

foobar

{% block kk_qanda_detail %}
    
        
            
                {{ $t('kk-qanda.detail.cancelButtonText') }}
            

            
                {{ $t('kk-qanda.detail.saveButtonText') }}
            
        

        
            
                
                    
                    

                    
                    
                
            
        
    
{% endblock %}

Die Seite mit dem Listing funktioniert soweit. Die create/detail Seite gibt nur den foobar Tag aus, sonst nichts.

Es gibt auch keine Errors im dev log. Hat jemand eine Idee?
