            Bug ID: 55396
           Summary: Formula added before referenced sheet wipes out
                    formula causes exceptions
           Product: POI
           Version: 3.9
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HSSF
          Assignee: dev@poi.apache.org
          Reporter: ebyrob@gmail.com

Created attachment 30718
  --> https://issues.apache.org/bugzilla/attachment.cgi?id=30718&action=edit
java main() putting formula before sheet create

1) Create a workbook.
2) Add sheet "X"
3) Add cell formula at 0,0 "=2+Y!A1"
  --> getCellFormula() has lost "Y" sheet name
4) Evaluate cell's formula
  --> java.lang.IllegalArgumentException: Invalid sheetIndex: -1.

I'm not sure if this is by design, but it can make it difficult to write a
library that outputs formulas and sheets in a convenient order.  (sometimes
sheet may not exist, but it's a good time to add the formula anyways.  Excel
itself shows #VALUE on screen but doesn't wipe out the cell's formula which may
be restored by clicking.)
