Fatal error: Call to undefined method

Good afternoon, I made a form and then add and change some of the same fields, for example the field NAME by the name LASTNAME, synchronize the table. (Clarified that use the data dictionary because I’m doing a system in three languages) . When I run the application throws me the following error “Fatal error: Call to undefined method form_cliente_1_apl :: nm_tira_formatacao_apellido () in …”. If anyone knows how to solve this from the SC environment it is appreciated.
Greetings!
