Perguntas MVC modelo 3 - incluir não funciona

Boa tarde, estou tentando criar uma browser utilizando MVC, quando clico na opção incluir não acontece nada, quando debugo fica parado no retorno da rotina:

Return aRotina

Mas não informa erro nenhum.
Alguém tem alguma ideia?
Segue o código abaixo:


/*
******
*/
User Function MVC_ZPF

Local cAlias := "ZPF"
Local cTitle := "Controle de EPI"
Local oBrowse := FWMBrowse():New()

Private aRotina := MenuDef()

oBrowse:SetAlias(cAlias)
oBrowse:SetDescription(cTitle)

oBrowse:Activate()

Return NIL

//

//

Static Function MenuDef()

Private aRotina := {}

ADD OPTION aRotina TITLE "Pesquisar" ACTION "PESQBRW" OPERATION 1 ACCESS 0
ADD OPTION aRotina TITLE "Visualizar" ACTION "VIEWDEF.M3_MVC" OPERATION 2 ACCESS 0
ADD OPTION aRotina TITLE "Incluir" ACTION "VIEWDEF.M3_MVC" OPERATION 3 ACCESS 0

ADD OPTION aRotina TITLE "Imprimir" ACTION "VIEWDEF.M3_MVC" OPERATION 8 ACCESS 0

Return aRotina
