*control combobox bugs?

Here is a simple script:
<<<<<<<<<<<<<<<Start of script>>>>>>>>>>>>>>>>>
 static TB = cl.Create("TestBar", 1)
local Width = 100
setstring Quote "

TB.Insert(0)
TB.SetLabel(0, "*control combobox dropdown " ++ Quote ++ "first|second|third" ++ Quote)
TB.SetWidth(0, Width)
TB.SetId(0, "Combo")

cl.AddCtrlListItem("TestBar", 0, "forth", -1)                //doesn't work
TB.AddCtrlListItem(0, "fifth")                        //doesn't work
cl.AddCtrlListItem("TestBar", 0, Quote ++ "sixth" ++ Quote, -1)        //doesn't work
TB.AddCtrlListItem(0, Quote ++ "seventh" ++ Quote, -1)            //doesn't work
cl.AddCtrlListItem("TestBar", 0, Quote ++ "eighth" ++ Quote)        //doesn't work
TB.ClearCtrlList(0)                            //doesn't work

TB.Insert(0)
TB.SetLabel(0, "OK")
TB.SetWidth(0, Width)
TB.AddLeft(0, cb("@GetInfo"))

TB.SetProperties("Format=barsize position: leftcaption vertical")
*bar Show TestBar

quit

Function GetInfo
win.debug(TB.GetId("Combo"), ": ", TB.GetCtrlValue("Combo"))
TB.close
quit
 <<<<<<<<<<<<<<<End of script>>>>>>>>>>>>>>>>>

 Comments say that AddCtrlListItem and ClearCtrlList commands don't work.
 I haven't tested all cl commands with *control buttons, but most of them work.
 Is this a bug or I did something wrong?

 

 Thanks
