Hi Paulo,
in Version 1.01 / Paulo 126 of iText the bug with the infinite loop in very
big table cells and "cellsfitpage" set to "true" seems to be still there.
Do we have to pull a newer version from CVS?
Thanks,
Peter
An Example code:
public class TableLooping {
public static void main(String[] args) {
Document document = new Document(PageSize.A4, 50, 50, 50,
50);
try {
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream("c:/temp/TableLooping.pdf"));
document.open();
PdfContentByte cb = writer.getDirectContent();
document.newPage();
Table table = new Table(2);
table.setCellsFitPage(true);
Cell aCell = new Cell();
for (int i = 1; i <= 100; ++i) {
aCell.add(new Chunk("this is a short
text"));
}
for (int k = 1; k <= 5; ++k) {
table.addCell(aCell);
}
document.add(table);
document.close();
System.out.println("Finished.");
}
catch (Exception e) {
e.printStackTrace();
}
}
}

Betreff: RE: [iText-questions] very strange error with itext, please
help
Are you using the last iText version?
There was a problem with Table that caused an infinite loop.
Best Regards,
