I am trying to inject a self created service & the angular2 Http service into my custom HttpRest service.
using
@Inject(Http) public _http: Http
worked fine, but when I try to inject another self made service i get following Error:
EXCEPTION: Cannot resolve all parameters for 'HttpRest'(Http @Inject(Http), undefined @Inject(undefined)). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'HttpRest' is decorated with Injectable.
For some reason UserIds is undefined, even though the import is succesful. My custom service:
@Injectable()
export class UserIds{
private _signature_id:string;
private _role_id:number;
get signature_id():string{
return this._signature_id;
}
set signature_id(id:string){
this._signature_id = id;
}
get role_id():number{
return this._role_id;
}
set role_id(id:number){
this._role_id = id;
}
}
The Custom HttpRest service im injecting both Http & UserIds into:
@Injectable()
export class HttpRest{
groups;
constructor(
@Inject(Http) public _http: Http,
@Inject(UserIds) public _ids: UserIds
){}
...
}
NOTE! when I remove
,
@Inject(UserIds) public _ids: UserIds
I dont get the Error.
What am I missing ?
UPDATE
The problem is actually that UserIds is undefined in the constructor params for some unknown reason that im trying to understand, so the title of this question becomes irrelevant. It should be "Imported service is undefined in constructors params".
Please reffer to my answer on this question further down this post.
UPDATE:
Please reffer to a question that discusses this issue.
