It might be specific to the type of your OLE object. What exactly did
you copy/paste into your slide?
I did a simple test that passed OK to me:
- create a presentation with a blank slide
- go to Insert / Object and insert PowerPoint Slide
- save
- run your sample code against the created file
- open the result in PowerPoint 2010 and test that the embedded
object is editable
So far all is fine on the POI side.
Can you please run the following code and verify the result:
OPCPackage pkg = OPCPackage.open(args[0]);
pkg.save(new File(args[1]));
pkg.close();
It will test your hypothesis that the OPC package is not properly
constructed when there is an embedded OLE object among package parts.
