[BUG]
When I run the attached file through FOP, I get the following error. Please
note that as suggested in
a reply to a previous posting, I have increased the memory size by using
-mx100m (and even -mx200m),
but I still get the same error.
HELP !!!!!!
Thanks very much in advance.
Regards
Paul

Stefano,
I have seen this a while ago..
If my memory still serves, I think it has to do
with region-before and region after overflowing, i.e taking
more area than is allocated for them..

I've been bugged by ArrayIndexOutOfBoundsException as well, but was not
really able to reproduce it or understand what was going on .... sounds
like a problem with area overflow BTW....
Sorry but I don't have any more indication :(

Re: [BUG] and WARNING : read this !!!
Posted by Keiron Liddle <ke...@aftexsw.com>.
After reading the warning I now know why it was stuck in the infinite loop. There is
a serious problem with a 'break-after="page"' inside a block in a table. This causes
FOP to keep creating more and more pages, as a result the JVM keeps using more
memory, in the case of a unix machine this could cause it to run out of memory and
crash (isn't unix great sometimes).
So the bugs are:
- if a static region contains data that overflows the area it causes an
"ArrayIndexOutOfBoundsException" due to being layed out twice and the overflow
setting the start text position to -1
- putting a page break in a table causes an infinite loop.

Re: [BUG]

After a bit of a look at your fo file I have a better idea of what is
causing the
problem, although I'm still not sure what is the ultimate cause.
In the class FOText the variable 'this.marker' is -1 when it is adding
text to the
BlockArea. From my reading of the code this can only hapen if the FOText
object is
being layed out twice (ie. layout() is being called twice).
It seems a Static area is being layed out for each page, which may be
causing the
problem.
I could not easily read the file since the lines are extremely long,
maybe you
could try adding some more line breaks in the fo file.
I tried removing all the static regions. The file no longer seemed to
have the same problem. BUT the rest of the file seemed to cause fop to
go into an infinite loop (after 20,000 pages I gave up). I'm guessing
there is a problem with the tables.
I don't know the code well enough to fix the array problem properly.
Your best option may be to restructure the fo file.
