Dockable Windows: New Features Guide for SAP PowerBuilder 12.6

Question

I copied the example in the SAP document: PowerBuilder-NewFeatures.pdf at page 21.
4.2.7
Opening Docked Windows and Tabbed Document Windows
Sample code for opening docked windows and tabbed documents.
Context
Procedure
1. Create a window w_sheet_any as a main!window type.
2. In the open event of w_sheet_any, add this code:
string ls_i
ls_i = Message.stringparm
if not isnull(ls_i) and ls_i <> "" then
this.title = ls_i
end if
3. Create an MDIDock window w_mdidock_dockstate and set any menu in it.
4. In the open event of w_mdidock_dockstate, add this code:
window win[]
OpenSheetWithParmDocked(win[1], "1", "w_sheet_any", this, WindowDockLeft!, "")
OpenSheetWithParmInTabGroup(win[2], "2", "w_sheet_any", this, "")                                             <<<<<<<<========
OpensheetWithParmInTabGroup(win[3], "3", "w_sheet_any", win[1], "")
OpenSheetWithParmAsDocument(win[4], "4", "w_sheet_any", this, "")
OpenSheetWithParmAsDocument(win[5], "5", "w_sheet_any", win[4], "")
OpenSheetWithParmAsDocument(win[6], "6", "w_sheet_any", this, "", false)
OpenSheetWithParmAsDocument(win[7], "7", "w_sheet_any", win[5], "")
OpenSheetWithParmAsDocument(win[8], "8", "w_sheet_any", win[6], "")
5. Run the application.
You will see windows 1 and 3 as a tabbed group, with the tabs at the bottom. Sheets 4, 5, and 7 appear as
tabbed doc
WHY THE SECOND OPEN DOES NOT WORK ?

Hi.
Even in beta the example provided needed some corrections. But instead of using the example on the pdf, why don't you take a look at the MDIDockingDemo Project included in the code examples? (See the screenshot... It's not PB.NET )
