jqxValidatorComponent in Augular 2

[andreaParticipant]

I have a problem with jqxValidatorComponent in Angular 2,
from typescript the following call works fine also according to the example:
this.myValidator.validate(document.getElementById(‘formUserDetail’));

but I’m not able to use the onSuccess:
this.myValidator.onSuccess(this.onSaveContinue)

I receive an error “Cannot read property ‘username’ of undefined”

The typescript method normally works, but not from onSuccess:

user:any = new Object();
onSaveContinue(): void
{
if (this.user.username==null) {
….
}
}

Is there a way to make it work?
Thanks
Andrea

After some investigation I found out that this seams to be a known issue in typescript, described here:

typescript-class-method-this

As described in the link a possible workaround is to change the method signature as follow:

onSaveContinue = () => {
  if (this.user.username==null) {
     ….
  }
}

This works properly with onSuccess:
this.myValidator.onSuccess(this.onSaveContinue);
