Angular2 If ngModel is used within a form tag, either the name attribute must be set or the form

Question

I am getting this error from Angular 2

core.umd.js:5995 EXCEPTION: Uncaught (in promise): Error: Error in app/model_exposure_currencies/model_exposure_cu

Answer 1

For everyone who don't panic with the error message itself, but just googling for the explanation why example from here doesn't work (i.e dynamical filtering doesn't occur when the text is typed into the input field): it will not work until you will add the name parameter in the input field. Nothing points to the explanation why pipe isn't working, but the error message points to this topic and fixing it according to the accepted answer makes the dynamical filter working.
