Posting an initiative to an existing issue

Works fine for existing issues. But if posting a new initiative to an issue created on-the-fly (i.e. an issue not already stored in models/issue.js), then issue title will be blank when the new initiatives form is displayed, after clicking "Start an initiative for this issue". Is this just an Ember Data thing that we don't have to worry about for the real app, which will use an actual model database on the server?
how should we proceed here?
