[kashimliox]

hello everyone ,
find a problem in pptx file editing.

pom dependencies as following:

<dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi</artifactId>
          <version>5.5.1</version>
      </dependency>
      <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-ooxml</artifactId>

          <artifactId>poi-scratchpad</artifactId>
          <version>5.5.1</version>
      </dependency>

Microsoft Office 365 version ：2511（19426.20218）

when i use following code to copy a slide from template pptx to a target one, 'If you trust the source of this presentation,click Repair' comes out .

  XSLFSlide newSlide = ppt.createSlide(sourceSlide.getSlideLayout()); 
            newSlide.importContent(sourceSlide);

waiting for reply.

here comes the attachment and test code

PPTdemo.java

pom.xml

[kashimliox]

红黄 -无嵌入 -纯色 - 副本5.pptx

this is the pptx template file

[kashimliox]

In the template file ,if a shape was copied from a slide page to another page ,
then use the template file to make a new pptx file with the following code ,

  XSLFSlide newSlide = ppt.createSlide(sourceSlide.getSlideLayout()); 
            newSlide.importContent(sourceSlide);

then the problem happened

After some digging I am afraid this caused by some PPT content not supported fully in POI.

Your code, adding slides into the same presentation, produces "Cannot open the file: A shared part is referenced by multiple source parts with a different relationship type." validation error in the Open XML SDK Productivity Tool.

I've tried to modify the code to copy slides into the new presentation. That validation issue has gone, but the output is still reported as corrupted in PowerPoint. Unfortunately, in this case we have no clue why.

When trying the same code with simple slides only with text and images, the cloning works correctly.

@jan-tosovsky-cz
thanks ,hope poi will fix this problem in the future version.
but it now can be opened normally in wps application

I can only persuade the user to use WPS.....

@jan-tosovsky-cz
