unshift
returns the new length of the array, and not the array itself.
you can do unshift
first, and then return the array instead.
@computed get countries() {
var empty = { id: 0, name: '' };
var test = this.referencedata.filter(x => x.propertyname === "country");
test.unshift(empty);
return test;
}
