this.state.dataRecord = this.props.ds.record.getRecord('data');
          this.state.profileRecord.whenReady(() => {
            this.state.dataRecord.whenReady(() => {
              if (!this.state.profileRecord.get("onboardingComplete")) {
                Actions.onboard({ds: this.props.ds, username: this.state.username, profileRecord: this.state.profileRecord, dataRecord: this.state.dataRecord, configurePush: this.props.configurePush});
              } else {
                var configurePush = this.props.configurePush.bind(this)
                configurePush()
                Actions.reset('drawer', {ds: this.props.ds, username: this.state.username, profileRecord: this.state.profileRecord, dataRecord: this.state.dataRecord, configurePush: this.props.configurePush});
