We need to show an error message if the user has not made a selection or the input returned an empty search.
This change adds an extra
matchCountproperty to theautocompleteCoreclass which stores the number of items matched by the inputmatchCountis set to one when the user makes a selection using a valid option.The vue component, in turn emits a 'valid' event that contains an object with two properties:
isValid{boolean} - whether or not the current state is validmatchCount{number} - items returned by the search, or1if user has made a selection.The
validis emitted on every key stroke, submit & change and can be used by the client code to show/hide error messages.
