merging pptx drops template

[Lo...@log-net.com]

I just noticed that when I merged pptx files (creating a new pptx), the 
slide templates are gone.  The code I am using is basically:

XMLSlideShow newppt = new XMLSlideShow();
for(String ndx : deckIndexes) {
        int iNdx = Integer.parseInt(ndx);
        XSLFSlide slide = coreSlides[iNdx];
        if(slide!=null) {
                newppt.createSlide().importContent(slide);  //THIS IS THE 
CODE!!!
        }
}

I'm guessing I'm going to have to dip deeper into the slides, but I want 
to be 100% sure before I go down that road.

Thanks,
Lou

A slide contents consists of two components:
1. shapes that actually present on the slide
2. shapes defined on the slide master. For example, if slide master
has a picture background then all slides that follow it will show this
picture even if the picture is not physically defined on the slide.

Slide#importContent imports (1), that is, it imports only the actual
slide contents.
In theory this approach can be used for master sheets too, but it
wasn't tested. Try to get slide's layout and slide's master and call
importContent on them. What is the result?

I think I may have solved my own issue by simply creating the new slide 
show a different way:

XMLSlideShow newppt = coreppt;
XSLFSlide[] newSlides = newppt.getSlides();
for(int slideIndex=newSlides.length-1;slideIndex>=0;slideIndex--) {
        if(deckIndexes.contains(Integer.toString(slideIndex))) { 
//deckIndexes is a list of slide indexes that must be in the new show - 
basically a filter
                //do nothing - keep the slide
        } else {
                newppt.removeSlide(slideIndex);
        }
}

This seems to be working OK.  If anyone sees anything I am missing, please 
let me know.
