Angular. Problem with custom validator

I have a field that requires conditional validation.


If a certain dropdown value is chosen then I need the field to be required.  No problem with one field and custom validator.  Unfortunately its email field and I have to add pattern and standard email validators too and this is causing me a nightmare to implement.


Currently the following works for required:


  
 proofEmail: ['',conditionalValidator( (()=> this.isProofPDF === true),Validators.required)],

Open in new window


My conditionalValidator function here:


function conditionalValidator(condition: (()=> boolean), validator : ValidatorFn): ValidatorFn {
  return (control : AbstractControl):{[key:string]:any} => {
    if(! condition()){       return null;     }     return validator(control);   }

Open in new window


My html here:


 <input class="form-control" formControlName='proofEmail' id="proof-email">

Open in new window

So Im simply trying to add validators.email and validators.pattern(mypattern) 

here



 but no matter what I try I cant get it right.  When I add validators at runtime i have a different set of issues.  Hope someone can help.
