I have a problem setting belongsTo relationship on newly created record. Simply I have to objects:
Checklist with:
```
user: DS.belongsTo('user', {
async: true,
inverse: 'checklists'
})
```
User with:
```
checklists: DS.hasMany('checklist', {
async: true,
inverse: 'user'
})
```
I’m trying to create new checklist object:
```
var checklist = this.store.createRecord('checklist', {
name: this.get('checklistName'),
user: this.get('currentUser')
});
checklist.save();
```
Name is set up correctly from controller. currentUser keeps valid user object of course, however it’s not set. When the request hits API it lacks user parameter:
```
{
checklist: {
name: 'Name'
}
}
```
When I remove “async” parameter from checklist model it apparently works. What may cause that?

I ran into this issue a couple of months ago. There is something that just drops changes when it’s async. I tried several methods at the time, even some private methods (and setting \_data directly). I just ended up setting it to not be async.
It’s worth noting that the [Ember Data 1.0-beta3 ChangeLog](https://github.com/emberjs/data/blob/master/CHANGELOG.md#ember-data-100-beta3-september-28-2013) says that they fixed “async belongsTo” back in September. Check that you’re using a recent version. If it’s still failing, boil it down to a simple test case on (e.g.) JSBin and file a bug report on Github.
