Hiya, I upgraded to version itext-1.01.jar and recompiled all my codes. The problem remains. After some further testing, i notice when I set the custom width of the columns instead of using the default equal width distribution the out of memory error went away. Since 3 of the columns in my table contain very long strings of texts, i made the width of those columns much wider than others (which contains just an integer). I really dont feel comfortable moving this into production from dev without knowing why it's doing this.
The fundamental problem is still why would a 20 page pdf generate out of memory errors, and why would everything work fine after removing a blank row or changing the column width. It just doesnt make sense, paulo or anyone can you shed some light on what would cause an out of memory exception other than a very large pdf?
Also it seems my program satisfy peter's description - very big table cells(the 3 text columns) and cellsfitpage==true, could it be a bug then? if so, any work around?
thank you much,
gaga

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

Are you using the last iText version?
There was a problem with Table that caused an infinite loop.
