1. table populated from server

// table
{{#each content itemController='record'}}
...
{{/each}}

2. user clicks [add record]

content.pushObject(recordInstance); // isNew
// instance is now in table

3. user fills out instance data
4. user hits save

// in RecordController
record.save();

Instance stays in table, and store.filter also adds the instance from the server.

After removing content.pushObject(recordInstance), the record is still added to the table, but once saved a new one is created as well..

Maybe because the first one has no id?
