Description Cesare Mauri 2019-10-28 13:11:51 UTC 
After modifiing data in a slide than contains more than one chart an exception is thrown because excel name is not unique.
Original template contains:
/ppt/embeddings/Microsoft_Excel_Worksheet0.xlsx
/ppt/embeddings/Microsoft_Excel_Worksheet1.xlsx
and so on, but after processing numbering is lost:



org.apache.poi.openxml4j.exceptions.PartAlreadyExistsException: A part with the name '/ppt/embeddings/Microsoft_Excel_Worksheet0.xlsx' already exists : Packages shall not contain equivalent part names and package implementers shall neither create nor recognize packages with equivalent part names.

Comment 1 Cesare Mauri 2019-10-28 13:17:35 UTC 
Note: I started from a pptx created from openoffice, if I make the same from a msoffice file the problem doesn't occur but final file is corrupted (openoffice opens it but msoffice not)

http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/xslf/usermodel/BarChartDemo.java present the same problem (corrupted pptx file when template is saved and than opened from msoffice)
