Using router-view inside template replace-part

[valichek]

I have code like:

<my-comp>
    <template replace-part="middle">
      <router-view containerless></router-view>
    </template>
</my-comp>

I get Error: There was no router-view found in the view when I navigate to that page from other page, but it renders ok when enter that page directly.
So question: Is this code good or tricky?

The router view needs to be inside the view to which the view model's router is associated.When you use a template part, you are specifying to take that router view out of the current view and render it inside the internal view of the my-comp. So, the router view is no longer present and thus no router view is found.
