Cannot call vm.$dispatch for Vue

Simcon commented 5 years ago

I've taken the Vue From Scratch example and I'm trying to get the button click to work as shown in http://www.dotnetify.net/core/examples/controltypes,

In the browser console I get a 'vm.$dispatch is not a function' message.

I'm wondering if it's because I'm outside of a vue template (similar to https://github.com/dsuryd/dotNetify/issues/136). If so, how can I make this work?

            <p><button class="btn btn-secondary" type="button" @click="onButtonClick">Click me</button></p>

        methods: {
            onButtonClick: function () {
              vm.$dispatch({ ButtonClicked: true });
            }        
        }
      })

        public Action<bool> ButtonClicked => _ =>

            _timer = new Timer(state =>
            {
                Changed(nameof(ServerTime));
                PushUpdates();
            }, null, 0, 1000);
        }

        public override void Dispose() => _timer.Dispose();
    }
}

The vm is dotnetify’s and not Vue’s:

this.vm = dotnetify.vue.connect(...
...
this.vm.$dispatch(...

Of course! Well that's a little embarrassing. Confirmed working - thanks!
