            Bug ID: 116850
           Summary: The Undo command does not undo parts of the changes
                    made by setting a DataArray from user code.
           Product: LibreOffice
           Version: 3.5.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: jag at psilosoph.de

Description:
Generally changes made by execution of user code are subject to the Undo
command. This also applies if the DataArray of a CellRange is set from BASIC.
However, if by such an action cells that previously were blank get content, the
action is not undone insofar. 
Even more clearly: Calling Undo (Ctrl+Z) after setting a DataArray by user code
previous content that was changed by myRange.SetDataArray() is reinstated.
Cells that were blank previously retain the content they got by the action.

Steps to Reproduce:
1. Open the attached example and permit macros.
2. Perform the steps precisely described there.


Actual Results:  
As already described.

Expected Results:
As already described.


Reproducible: Always


User Profile Reset: No



Additional Info:
Is this form new? I don't like it. 
For all the bugs I reported in the last few years I used a much simpler
procedure, and was able to attach my demo file at the same time.
