How to Populate a List with Objects in Angular 2 using Typescript

Currently, I'm encountering an issue with adding data to a list using the following code snippet.

labelListSelected: Label[];

onChange(object, flag){
   if(flag==false){      
           this.labelListSelected.push(object);
   }
   console.log(this.labelListSelected);
     //   console.log(object.Id+" : "+flag);
}

Answer №1

Looks like the issue is a null pointer exception. To fix it, switch to:

selectedLabels: Label[] = [];
