Persisted data not immediately retrievable

Persisted data not immediately retrievable

Data is entered in Field 1 of Form A (stateless)  and used to fetch records from the database.
Using "actions upon user input" the fetched records are persists to Form B (not stateless).
Field 2 of Form A is a "look up field" which searches Form B for the newly persisted data.
The look up field does not find any data until Form A is refreshed.
Is there a way to have the newly persisted data to Form B be immediately available for the look up Field 2 in Form A without having to leave or refresh the form?
Any tips would be appreciated. Thanks.
