Slide Source and Destination (couple Printshots)

Have a presentation with a chart and some notes.

Running the code below using the resources attached to this issue (src.pptx) generates the dst.pptx, such file is not being generated correctly, charts and notes are missing as shown in the attached pictures. The dst file can not be opened using powerpoint.

I also experience this bug. 
It seems POI succeeds in copying object, but fails in the type. 
Calling "getShapeName" results in the same name, but when trying to convert, here is what it says: 
org.apache.poi.POIXMLDocumentPart cannot be cast to org.apache.poi.xslf.usermodel.XSLFChart
org.apache.poi.xslf.usermodel.XSLFPictureData cannot be cast to org.apache.poi.xslf.usermodel.XSLFChart

Good news: the generated XML for the new chart object is the same as the original XML. 
The relation ID is the same (in my case, "rId2"). 

However, when checking in relations file for the slide, "rId2" is not bound to a chart anymore, but to an image. 
Also, some relations are simply missing. 

This seems to be a bug about relationships.

When digging in PPTX archive, the charts are not copied. I have as many charts in the new files than in the original one.

Encountering the exact same bug, that prevents me from using POI to generate power point presentations : I don't see how to *insert* graphs while building a presentation because of this bug.
Comment 4 Alain Fagot Bearez 2017-09-13 17:31:18 UTC
A partial fix (only handling the charts) is available as pull request #68:


However the changes are not focused in solving only this issue, but in preparing for a shared code base for charts handling.
Comment 5 Alain Fagot Bearez 2021-02-08 20:37:42 UTC
While importing the charts has been available since POI 4.0.0, only with revision  r1886338 are the notes also imported.
