Combobox value safety (in case of undefined)

[huineng]

I refer to this code

carbon-components-angular/src/combobox/combobox.component.ts

Line 604 in 17da1f5

writeValue(value: any) {

There can be circumstances that value is undefined

If that is the case and the type is multi, it will generate an error (value is not iterable)

I simply suggest to add an if statement

if (value) {
	for (const v of value) {
		for (const item of this.view.getListItems()) {
			if (item[this.itemValueKey] === v) {
				newValues.push(Object.assign({}, item, { selected: true }));
			}
		}
	}
}

"carbon-components-angular": "^5.27.4"

thanks
