HI ,
com.lowagie.text.exceptions.IllegalPdfSyntaxException: Unbalanced
save/restore state operators
give me sugetion how to debug *itext* code when the have face this
type of exceptions
I searched In but not find suitable answer.

Search not further, just read the error message: you have unbalanced
save/restore state operators.
In other words, somewhere you have used the method saveState() without
using restoreState().
Or you have used restoreState() without using saveState().
Or maybe you have something like:

cb.saveState();
document.newPage();
cb.restoreState();

In older versions of iText, we allowed developers to write PDF syntax
any which way they want.
Unfortunately, when you give this power to developers who didn't read
and understand ISO-32000-1 (the standard you've probably read whilst
searching for a suitable answer), you end up with PDFs that are corrupt.
That's why we took away a little bit of that power. In order to make
iText more "fool-proof", we now throw an exception when a developer
doesn't respect the q/Q-rule.

I am getting the same error when I try to add multiple PdfPTable objects to a
document.

doc.add(table1);
doc.add(table2);
doc.close();

The thread mentioned doing a cb.saveState() and a cb.restoreState(). What
is "cb"?? Thanks.

I'm not using an old version.  I downloaded version 5.5.8 last Thursday to upgrade from a really old version I was using.  When I downloaded new version 5.5.8 is when my problem started.  Please advise.  Thanks.

glennr,

I'm not using an old version.  I downloaded version 5.5.8 last Thursday to
upgrade from a really old version I was using.  When I downloaded new
version 5.5.8 is when my problem started.
I am getting the same error when I try to add multiple PdfPTable objects
to a document.

in response to a message about a
com.lowagie.text.exceptions.IllegalPdfSyntaxException - and if you indeed
got a com.LOWAGIE.... exception, you ARE using a version that dates from at
least July 2009.

If you merely did not read carefully what you responded to and actually got
a com.ITEXTPDF.... exception, please share a runnable example

Regards, Michael

Thanks for your quick response.

See attached example files with my report. ReportManager is the main driver
class that sets variables and makes the call to generate the warrant report.
This is a prototype so please excuse all the commented code of different
things I am trying.
