[Bug 65934] New: removed textparagraphs remain visible in slideshow
https://bz.apache.org/bugzilla/show_bug.cgi?id=65934
Bug ID: 65934
Summary: removed textparagraphs remain visible in slideshow
Product: POI
Version: 5.2.0-FINAL
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: XSLF
Assignee: dev@poi.apache.org
Reporter: bugzilla-apache@outlook.com
Target Milestone: ---
When a textparagraph is deleted, programmatically it seems as if the deletion
has been applied. However, the textparagraph is still visible in the slide of
the slideshow. (The same problem occurs with textruns, cf. another filed bug.)
Steps to reproduce:
@Test
void removeTextParagraph() throws IOException {
final XMLSlideShow ppt = new XMLSlideShow();
final XSLFSlide slide = ppt.createSlide();;
final XSLFTextBox textBox = slide.createTextBox();
textBox.setAnchor(new Rectangle(0, 0, 100, 100));
textBox.getTextParagraphs().get(0).getTextRuns().get(0).setText("lorem");
textBox.addNewTextParagraph().addNewTextRun().setText("ipsum");
textBox.addNewTextParagraph().addNewTextRun().setText("dolor");
assertEquals(3, textBox.getTextParagraphs().size());
assertEquals("lorem\nipsum\ndolor", textBox.getText());
assertEquals("lorem", textBox.getTextParagraphs().get(0).getText());
assertEquals("ipsum", textBox.getTextParagraphs().get(1).getText());
assertEquals("dolor", textBox.getTextParagraphs().get(2).getText());
textBox.getTextParagraphs().remove(textBox.getTextParagraphs().get(1));
assertEquals(2, textBox.getTextParagraphs().size());
assertEquals("lorem\ndolor", textBox.getText());
assertEquals("lorem", textBox.getTextParagraphs().get(0).getText());
assertEquals("dolor", textBox.getTextParagraphs().get(1).getText());
String filepath = System.getProperty("java.io.tmpdir") + "tmp.pptx";
FileOutputStream fos = new FileOutputStream(filepath);
ppt.write(fos);
fos.close();
System.out.println("file written to " + filepath);
}

I added r1898668 - would you be in a position to test this? The problem is that
textBox.getTextParagraphs().remove(...) does not remove the underlying XMLBeans
data (CTTextParagraph class).
If you want to work around the issue without my change, you can get the
CTTextBody for the XSLFTextBox using textBox.getTextBody().getXmlObject(). You
can then iterate over the 'p' array to find the right CTTextParagraph to
remove.

I was able to verify that the change works.
The above test initially failed with an UnsupportedOperationException. Great
idea to change the list of textparagraphs to Collections.unmodifiableList. :-)
After replacing the line
textBox.getTextParagraphs().remove(textBox.getTextParagraphs().get(1));
with
textBox.removeTextParagraph(textBox.getTextParagraphs().get(1));
the test passed again and the slide finally looks as expected.
Thanks for fixing the issue!
