angular2, rxjs Observables and datasource
posted

How can I set an Observable returned by angular2 http service as a grid's (or any other control's for that matter) datasource?

I've reviewed the samples on github but there all the data is populated right in the component's constructor.
Observables are async and by the time data is returned it's too late to bind it to the grid.

Actually, if I don't set grid's datasource to something righ in the constructor (or ngOnInit) I'm getting "Unexpected token u in JSON at position 0" right on line 335 of igniteui.anular2.js because datasource is 'undefined'.

Line 335 : this._dataSource = JSON.parse(JSON.stringify(this._config.dataSource));

Please help.
Thank you.
