Problem with Filter and Tdatabase

[Silvio.Falconi]

Please I have this function

Code: Select all | Expand

#include "fivewin.ch"

request dbfcdx

Function test 
     local oDbf
     local cdbfPath:= cFilePath(GetModuleFileName( GetInstance() ))  + "Data\"
     local nYear:= year(date())
     local   cFilter:= "LTRIM(STR(YEAR(FIELD->DATA)))= '" + ltrim(str(nyear)) + "'"
   

  oDbf:= TDatabase():Open( , cdbfPath+"LOTTO", "DBFCDX", .T. )
  oDbf:setorder(1)
  oDbf:GoTop()

          xbrowser odbf

        oDbf:SetFilter(cFilter)
        oDbf:GoTop()

     xbrowser odbf
return nil 

the index 1 is on DTOS(DATA)+CONCORSO

before the filter I see all archive



the filter seems good



After the filter it not show any records , why ?

It's strange because in the test I did, that is, in the procedure in a small dialog, everything works perfectly, but when I create an object class with all the functions of the procedure it doesn't work, that is, it doesn't find the data, there's definitely an error somewhere that I can't find.

this is basically what i'm doing, it seems complex but it's not
