BUT: powerpoint still shows the old data when I open the ppt. I have to refresh manually within powerpoint to get the new figures displayed. Is there any possibility to trigger the update automatically / programatically?
As I understand it, an embedded document is made up of two parts. One is the real document, the other is an EMF image of the rendering of that document. That way, opening the parent document is much quicker, as you don't have to open up potentially a dozen other office documents.
Unfortunately, as POI is unable to render office documents to an image (well, other than powerpoint files with a fair number of caveats), we can't re-generate the rendered version.
