Macro to open another form with selected data, or to create new data if "filtered" if not existing ...

I use macros from example in this post from file Open_Form_Filtered.odb, … but…

What if I don’t have filtered record in other form (no relation data created) … I need macro to open filtered data in another form or to create new record if data is not existend … well I can add data to opened form, but trouble is listbox in which if I select data (for new record) I get error, and nothing is entered (unless I disable macro for listbox)

So in short, error in on new record in listbox …

Now I use this…

Sub Otvori_Upisni_List_iz_Maticnog_Lista (oEvent As Object) 'This opens another form with filtered data
	oForm = oEvent.Source.Model.Parent
	oForm2 = ThisDatabaseDocument.FormDocuments.getByName("Upisni") 
	oForm3 = oForm2.Component.DrawPage.Forms.getByName("Upisni_List")
	oForm3.Filter="( ""UPISNI_LIST"".""FK_Maticni"" = " & iID & " )" 
end sub

Sub Refresh_MainForm (oEvent As Object) 'List Box > Execute (event)
   oForm = oEvent.Source.Model.Parent 
   oForm.updateRow() 'this is point where I get error when entering data to new record via listbox, ... changing data on existing records works fine
End Sub
