Printing assessments to pdf still fails with some HTML elements

In SAM-1106 it was fixed an issue when printing to pdf an assessment with HTML text which includes font changes.

We have found a happening of this issue not covered by the patch, related to PdfPTable objects.

The Description/Intro element in "Assessment Introduction" in Settings can be set as HTML and with a font-style medium or large it throws the Exception.

The involved code at PDFAssessmentBean.java is:

public ByteArrayOutputStream getStream() {
(...)
//parse out the elements from the html
ArrayList elementBuffer = HTMLWorker.parseToList(safeReader(head.toString()), style, props);
float[] singleWidth =

{1f}

;
PdfPTable single = new PdfPTable(singleWidth);
single.setWidthPercentage(100f);
PdfPCell cell = new PdfPCell();
cell.setBorderWidth(0);
for (int k = 0; k < elementBuffer.size(); k++)

{ cell.addElement((Element)elementBuffer.get(k)); }

single.addCell(cell);
(...)
document.add(single);
document.add(Chunk.NEWLINE);

The Element object is not processed by FormattedText and it also crashes.
