XSLFSlide originalSlide = presentation.getSlides.get(0) XSLFSlide newSlide = presentation.createSlide(originalSlide.getSlideLayout) newSlide.importContent(originalSlide) System.out.println(originalSlide.getXmlObject) System.out.println(newSlide.getXmlObject) If the slide contains an XSLFGroupShape, this shape is copied with its name. But all shapes contained in the group will miss their name. After following importContent workflow, copy code is here: https://svn.apache.org/repos/asf/poi/trunk/src/ooxml/java/org/apache/poi/xslf/usermodel/XSLFGroupShape.java When checking "copy" function, it creates new shapes, but they get a default name such as "TextBox 83"!
I tried to reproduce this with the current version of Apache POI, but could not. It seems this is already fixed since some time via other changes. I have added a corresponding unit-test in r1814440 to verify that it works as far as I see. If you still see a problem with this, please report a new issue together with a unit-test which allows to reproduce the problem.
