Code

class A {
	protected _oId: string;

	constructor(){
		this._oId = "";
	}

	public get oId(): string {
		return this._oId;
	}
}

class B extends A {
	constructor() {
		super();
	}

	public set oId(val: string) {
		this._oId = val;
	}
}

Expected behavior:

const b = new B();
b.oId = "123";
console.log(b.oId); // 123

If I understand #13432 right, it's a correct behaviour. But then it's not correct that getters and setters are inherited in general. I have to overwrite the getter function in my derived class to make the code work as expected. But then the benefit of inheritance is lost in that case, more concretely the inheritence makes no sense at this point because the logic of the parent class is lost. The main problem is that no exception occurres and it's hard to find the cause of this error.

Actual behavior:

const b = new B();
b.oId = "123";
console.log(b.oId); // undefined
