Bug ID: 57250
Summary: XMLSlideShow.setSlideOrder() produces corrupted
CTSlideIdList
Product: POI
Version: 3.11-dev
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: HSLF
Assignee: [email protected]
Reporter: [email protected]
I guess the bug was introduced by commit 1620997 (Bug 56854 - XMLBeans
performance when using getXXXList() and other proxy methods).
Tested with version 3.11-beta3.
The setSlideOrder() method removes old slide at wrong position:
after insert:
<xml-fragment xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main";
xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships";
xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main";>
<p:sldId id="257" r:id="rId7"/>
<p:sldId id="256" r:id="rId2"/>
<p:sldId id="257" r:id="rId7"/>
</xml-fragment>
after remove:
<xml-fragment xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main";
xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships";
xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main";>
<p:sldId id="257" r:id="rId7"/>
<p:sldId id="257" r:id="rId7"/>
</xml-fragment>
Finally the presentation refers to the same slide twice and the old slide is
not more reachable.
The following unit test fails (create a slide show insert-infront.pptx with a
single slide containing text "Test me"):
@Test
public void testInsertInfront() throws Exception {
XMLSlideShow ss =
XSLFTestDataSamples.openSampleDocument("insert-infront.pptx");
XSLFSlide slide;
assertEquals(1, ss.getSlides().length);
slide = ss.getSlides()[0];
assertContains(getSlideText(slide), "Test me");
slide = ss.createSlide();
ss.setSlideOrder(slide, 0);
slide.createTextBox().setText("New slide");
// Save and re-load
ss = XSLFTestDataSamples.writeOutAndReadBack(ss);
assertEquals(2, ss.getSlides().length);
slide = ss.getSlides()[0];
assertContains(getSlideText(slide), "New slide");
slide = ss.getSlides()[1];
assertContains(getSlideText(slide), "Test me");
}
