Summary



The user designed a field to use the Autocomplete control with a Data Page as its source, but the values from the Data Page do not display for the field. As a work around to this problem, the user provided a Data Page already loaded on the clipboard, but still the Data Page values do not display for the field. In addition to the unexpected results for the Autocomplete field, users see the error message.
