Meteor: Changing a subtemplate without changing parent template

问题

If I have the following template structure

 <template name="A">
            {{> B}}
            {{> C}}
    </template>

How can I have C update when it changes without having Template A re-render?

I've tried {{#isolate}}{{> C}}{{/isolate}} but this doesn't work and using a constant region isn't quite right either as this isn't a constant region.

回答1:

As of Meteor 0.7.0.1, re-rendering a sub-template causes the parent to re-render but not sibling templates. Isolate works the same way.

I put together a simple example of this that you can play with here:

Keep in mind that this behavior may change with the upcoming release of Meteor UI in preparation for Meteor 1.0.
