Current behavior
When using AutoComplete with objects and a numeric value then objects with value 0 are not displayed when preselected.
This is because 0 is a falsy value and therefore it is ignored in the first line of updateInputField().

updateInputField() {
  let formattedValue = this.value ? (this.field ? ObjectUtils.resolveFieldData(this.value, this.field)||'' : this.value) : '';
  ...
}

I solved this by replacing || with ??.

This is related to but not solved by #9628.

Expected behavior
When an object with value 0 (e.g. { name: 'test', value: 0}) is preselected then 0 should be displayed.

Hi @Timmeeeey,

Thanks for your suggestion, unfortunately '??' is not compatible with IE 11.
