I have added isrequired{string} : true property and

sling:resourceTyoe : granite/ui/components/foundation/form/autocomplete in dam asset dialog.

The error pop up and the red border that should appear for mandatory fields is not appearing .

However, when required{Boolean}:true property is added the validation ”Please fill out this field” is appearing but I am not able to save the form as the error dialog”

One or more required fields missing” appears.
