Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Unhandled promise rejection Error: Zone.js has detected that ZoneAwarePromise
(window|global).Promisehas been overwritten.Most likely cause is that a Promise polyfill has been loaded after Zone.js (Polyfilling Promise api is not necessary when zone.js is loaded. If you must load one, do so before loading zone.js.)

I mean in your code, import
equationsfirst.this should be the first line of your code:
hi @mdibaiee
I put import { Equation } from "equations"; at first line of my app.component.ts file but do the same
@Toso82 from what I understand of that error, Zone.js is asking you to import
equationsbeforezone@mdibaiee ok but i want to use this on angular 4 application. Import equations is on top and I don't impor in this module zone in app.component.ts
import { Equation } from "equations";
import { Component, OnInit, OnChanges, LOCALE_ID, Inject } from '@angular/core';
import { Subject } from './Model/mca.subject'
import { Comparabile } from './Model/mca.comparabile'
import { CaratteristicheService } from './caratteristiche.service'
import { Caratteristica, CaratteristicaInfo,TipoStima} from "./Model/mca.caratteristica";
import { Observable } from "rxjs/Observable";
import { DecimalPipe } from '@angular/common'
import { DialogService } from "ng2-bootstrap-modal";
import { EditCaratteristicheDialogComponent } from "app/component/edit-caratteristiche-dialog/edit-caratteristiche-dialog.component";
I don't know how to put before
@Toso82: Sorry, I really have no idea, maybe TypeScript is importing zone
