Hi folks,
I'm getting a beginText/endText imbalance that I think I've narrowed down to
NoNewLineParagraph or related functions. I'm using version 5.4.3 of
iTextPDF and XMLWorker to generate a PDF file from an HTML file. JRE 6. If
the length of a paragraph forces a newPage, it looks like things aren't(?)
getting cleaned up properly.
I've included below a sample application that reproduces the failure, an
input file, and a stack trace on an exception that occurs when the first
newPage() is encountered. That exception is later ignored. The real
problem is the beginText/endText imbalance when Document.close() is called
at the end.
As you'll see, I don't issue any beginText/endText. It's all handled by the
XMLWorkerHelper.
If you delete one character in the input file, everything is fine.
Coincidentally you also get exactly one complete page on the pdf file,
instead of running into the following page.
Am I missing something simple here?
Any help appreciated.
- Chuck
(Aside, are the files I've included below better sent as attachments, rather
than in-line?)
