validatie - stel fout " errors : {__zone_symbol__state: null, __zone_symbol__value: Array(0)}" in door Angular 4 validator

Mobile mobileNumberValidator werkt goed, maar de andere twee validators geven een null promise terug bij fouten. Ik kan de fout die ik hier heb gemaakt niet identificeren. Help alsjeblieft. Die twee validators zetten fouten in het formbuilder-object als volgt

fouten : {__zone_symbol__state: null, __zone_symbol__value: Array(0)}

In formulierbouwer groep

 this.empInfoForm = this.fb.group({
      'Mobile': [null, [Validators.required], [this.mobileNumberValidator.bind(this)]],
      'Private': [null,  [this.privateNumberValidator.bind(this)]],
      'Work': [null, [this.workNumberValidator.bind(this)]],  
    });

Antwoord #1

Ik heb de fout gevonden die ik hier heb gemaakt. De aangepaste validatorbinding moet hier de derde parameter zijn.

this.empInfoForm = this.fb.group({
      'Mobile': [null, [Validators.required], [this.mobileNumberValidator.bind(this)]],
      'Private': [null,null,[this.privateNumberValidator.bind(this)]],
      'Work': [null,null,[this.workNumberValidator.bind(this)]],  
    });

======================== Sol




// use platform ready function, its must

 this.platform.ready().then(() => {

        // use promise like syntax not like this.appVersion.getVersionNumber()
       
     this.appVersion.getVersionNumber().then((data) => {
            
            })

})
