Additional details

This is a workaround;

{{ collection:ipad :slug:is="get:page | replace('/', '')"  }}
  {{ collection:ipad :parent:is="id" }}
    <ul>
      <li>{{ title }}</li>
    </ul>
  {{ /collection:ipad }}
{{ /collection:ipad }}

But it would be nice to map the children tag when called within a collection to have the same expected results.

under the hood the children tag is just doing a {{ nav from="{url}" max_depth="1" }} so you could just do that instead as a workaround.

[duncanmcclean]

The {{ children }} tag is only intended to let you list the children of the current page. It won't work as expected inside a collection loop.

Under the hood, it's literally just doing this.

{{ nav:collection:pages :from="current_url" max_depth="1" }}
    {{ title }}
{{ /nav:collection:pages }}

In your context, you can swap out current_url for url and it should do what you're after.
