Hi Wilhelm,

I've take a look at this issue, and it's definitely on the complex side
and I don't really have the time to address this at present. Could you
explain why you need that empty  element? Removing that
inline construct would solve your issue in the short term (obviously not

with the following workaround it works as expected:

true


  

  
  





Hope that helps

well, I don't even look at the .fo files normally. I write in asciidoc 
and I use an


asciidoc -> .xml -> xsltproc -> .fo -> fop -> pdf

toolchain. So I really don't know where this element is from :-(

But I found another description for a workaround and I will try that 
later (and report).



Removing that
inline construct would solve your issue in the short term (obviously not
an actual fix for this bug.)

This looks like the NPE is occurring during layout, could you please

attached you find the offending test.fo (it was generated from test.xml).

Re: fop and hyphenation produces NullPointerException

2012-07-21 Thread mehdi houshmand 
Hi,

This looks like the NPE is occurring during layout, could you please
provide the FO that causes this issue? If you could, try and cut down the
FO as minimal as possible, just so that whomever looks at this issue can
find the problem as quickly as possible.

Thanks

Mehdi

Show the stack trace.

Quoting Wilhelm :

using fop-1.0 oder fop-1.1rc1 I get NullPointerExceptions if I enable
hyphenation (language=de).

Any hints?
