There is a way to do this?

[Pedro Lucas Oliva Braz]

Im trying to insert insert a new Entity (document) at mongo, but before I need call a meteor method to catch some sequence to it:

    public create(t: T): Observable<string> {
        return MeteorObservable.call("getSequence", this.service).map(seq => {
            t.seq = seq.padding;
            return this.collection.insert(t);
        });
    }

I have been in trouble with the return of Observable.
Someone did it before?

ps:
this.collection = export const Entities = new MongoObservable.Collection("entities");

Try this.collection.collection.insert if it exists

RxJS observables won't fire unless you subscribe them. So, this is not an issue related to meteor-rxjs.
You can try to do like below;

public create(t: T): Observable<string> {
        return MeteorObservable.call("getSequence", this.service).map(seq => {
        t.seq = seq.padding;
        return this.collection.insert(t);
}).subscribe(returnOfInsertion => {});
    }

Note that; the mutation on external variable inside mapis not recommended because it will be side effect. You can learn more using RxJS Documentation.
