having some trouble getting my ember routing to work, and I'm a bit confused if I am doing it right. Seems like there has been quite a few changes to this part, which can be a bit confusing. I hope someone can help me see what is going wrong here.

Sorry, no luck in getting it hosted yet, but I do have screenshots to illustrate:

I am having two problems with my current configuration.
When clicking on a link-to to return to the main screen (/, "refsets"), the contents of the child screen (/:publicid) gets prepended to the bottom of the main screen. This keeps stacking up as you navigate back and forth.
When clicking on the link-to for the buttons "show rules" or "show concepts", the screen goes blank, and ember returns this cryptic error (other custom and ember logging details provided, too):
Loading concepts in router ember.js:3227
GETing concepts for: {...} ember.js:3227
Rendering refset.concepts with default view <appkit@view:default::ember404>
Object {fullName: "view:refset.concepts"} ember.js:3227
Transitioned into 'refset.concepts' ember.js:3227
Uncaught TypeError: Cannot read property 'parentNode' of null ember.js:24102
Assertion failed: Emptying a view in the inBuffer state is not allowed and
should not happen under normal circumstances. Most likely there is a bug
in your application. This may be due to excessive property change notifications.

These problematic 'link-to' statements are located:

Most of the times I see this it's related to invalid HTML, mismatched divs/sections etc.
<section id="details">
{{outlet details}}
<section id="details">
should be
<section id="details">
{{outlet details}}
</section>
And in the plan.hbs section is misspelled as secion.
Additionally using the / as the concepts path seems to be confusing ember, it thinks that the url with the / at the end is still just refset (not concepts)
Router.map(function() {
this.resource('refsets', {path:'/'});
this.resource('create', {path:'/create'}, function(){});
this.resource('refset', {path:'/:publicId'}, function(){
this.route('concepts', {path:'concepts'});
this.route('plan', {path:'plan'});
});
});
