Olá. Comecei com ADVPL há poucos meses e estou criando um cadastro MVC. A tela aparece normalmente e carrega os dados já existentes na tabela, mas quando eu interajo com qualquer opção do Menu aparece o erro:

"THREAD ERROR (20/07/2022 12:05:47 argumento #0 , parâmetro oObj erro, previsto O->U on FWFORMVIEW:SETMODEL(FWFORMVIEW.PRW) 04/02/2022 16:14:28 line : 720"

Alguma ideia de como corrigir?

Segue o meu fonte:

#Include 'Protheus.ch'
#include 'parmtype.ch'

Static cTitulo := "Atividades"

user function CADZME()

Local aArea   := GetArea()
Local oBrowse := Nil

oBrowse := FWMBrowse():New()
oBrowse:SetAlias("ZME")
oBrowse:SetDescription(cTitulo)
oBrowse:Activate()

RestArea(aArea)

Return Nil

Return oView
