Loading document with TOC: BadMethodCallException (Cannot add PreserveText in Section.)

[lorenzadefanti]

Hello,

I'm generating a docx document from HTML with a table of contents.
The docx document is saved correctly, but when I try to generate a PDF from this docx, it doesn't work.

Generating the docx:

$phpWord = new PhpWord();

$titleSection = $phpWord->addSection();
Html::addHtml($titleSection, 'some title text');
$titleSection->addPageBreak();
$titleSection->addTitle('');
$titleSection->addTOC();

foreach ($stepContents as $stepContent) {
    $section = $phpWord->addSection();
    $footer = $section->addFooter();
    $footer->addPreserveText('p. {PAGE}');
    $html = $stepContent->getValue();
   Html::addHtml($section, $html);
}

Saving the docx:

$fileDir = "/tmp/";
$fileName = "filename.docx";
$file = $fileDir . $fileName;

$phpWord->save($file, "Word2007");

Generating the pdf:

if ($format == "pdf") {
    Settings::setPdfRenderer(Settings::PDF_RENDERER_TCPDF, './vendor/tecnick.com/tcpdf');

    $pdfPhpWord = IOFactory::load($file);

    $pdfFileName = "filename.pdf";
    $pdfFile = $fileDir . $pdfFileName;

    $pdfWriter = IOFactory::createWriter($pdfPhpWord, 'PDF');
    $pdfWriter->save($pdfFile, 'PDF');

    $content = file_get_contents($pdfFile);
}

This line: $pdfPhpWord = IOFactory::load($file); produces an error, independently of which PDF-Renderer I choose (I've tried with dompdf and mpdf too).

If I delete the TOC-line, I can generate the PDF correctly.
