HSSF Reading Formula Ref3DPtg : error with getExternSheetIndex

[Pascal Chanteux]

Hi,

I 've got some problems with the "getExternSheetIndex" method of the
Ref3DPtg class. It returns the referenced sheet index, but with some excel
files, this sheet index is erroneous. Does anyone have a workaround for this
?

Thanks,
Pascal
