templates.application.hbs

<h1>Welcome to {{appName}}</h1>

Clients

<ul>
{{#each model as |client|}}
  <li>ID: {{client.id}} hasDirtyAttributes: {{client.hasDirtyAttributes}} isCool: {{client.isCool}}</li>
{{/each}}
</ul>

total clients: {{model.length}}

Expected:
clicking the button should unload records 1 and 3.<br><br>

Actual:
Get an error because the filterBy('isCool').forEach(client => client.unloadRecord()) leaves `null` in `this.store.peekAll('client')`.<br><br>


<button {{action "unload"}}>
  Unload isCool=true and dirty records
 </button>
