BASE: problem after upgrade to LibreOffice 7 (ListIndex doesn't work)

After upgrade from LibreOffice 6.4.3 to 7.0.1 (Windows), Access2Base ListIndex property doesn’t work.

Sub ListBoxVlasnikOnFokus
	Dim ocListBox As Object
	Set ocListBox = getObject("Forms!Adresar poslovnih subjekata!List Box vlasnik")
	varListIndexVlasnkObrta = ocListBox.ListIndex
End Sub

Error #13 (Data type mismatch) occurred at line 1441 in Control._PropertyGet

Do I have to do something different to use the Access2Base library in LIbreOffice 7 Base?
