Pega out of the box control Auto-Complete gives you the ability to type in few characters and based on the characters it gives you back the results based on the Source provided which can be Data page, RD etc.
Auto-Complete as a control does not validate the value selected or typed in manually is valid according to the source list of values.
we found online for validations while using autocomplete. It doesnot work.I think we have a problem with one of the JS
Yes, if you enable "Allow Free Form input", users can enter free text in the autocomplete and it will not validate it by itself. In Result, your value will not be updated correctly in clipboard.
You can try few things. Try disabling the Free form input or try adding a refresh action on the on change of AutoComplete and add validation logic in some DT or activity for validation in there. That works.
