java - Slide background color in Apache POI -

-

i'm having problem using apache poi while generating .pptx file. i'm setting background color each slide this:

xmlslideshow ppt = new xmlslideshow();      for(int = 0; i<10; i++) {         color currentcolor = colors.get(random.nextint(colors.size()))          xslfslide currentslide = ppt.createslide();         currentslide.getbackground().setfillcolor(currentcolor);     }

but in every single slide background color 1 of last slide. if random colors each slide (blue, black, ...., yellow) slides have background color yellow.

what i'm doing wrong?

hope can me, thank you
