Using oXygen 13.2's DocBook FO stylesheets and FOP and the <programlisting> in the document below (hopefully the long lines didn't get wrapped by my mailer), when the 'hyphenate.verbatim' parameter is set to '1' in the transformation scenario, the transformation fails with the following message: ------------------------------------ System ID: Untitled1.xml Scenario: Docbook PDF duplicate XML file: Untitled1.xml XSL file: C:\Program Files\Oxygen XML Editor 13\frameworks\docbook\xsl\fo\docbook_custom.xsl Engine name: Apache FOP Severity: error Description: The process 'Apache FOP' ended with code: 1. The error was: ERROR - Exception java.lang.IllegalArgumentException: factor < 0; was: -1 at org.apache.fop.cli.InputHandlerFOP.transformTo(Unknown Source) at org.apache.fop.cli.InputHandlerFOP.renderTo(Unknown Source) at org.apache.fop.cli.Main.startFOP(Main.java:174) at org.apache.fop.cli.Main.main(Main.java:205) Caused by: java.lang.IllegalArgumentException: factor < 0; was: -1 at org.apache.fop.traits.MinOptMax.mult(MinOptMax.java:251) at org.apache.fop.layoutmgr.inline.TextLayoutManager.processWord(TextLayoutManager.java:825) ------------------------------------------------ This appears to be the same stack trace as error 3 in: http://www.oxygenxml.com/pipermail/oxygen-user/2011-December/003951.html and also appears to be fixed in FOP post-1.0: https://issues.apache.org/bugzilla/show_bug.cgi?id=49837 Installing a development version of FOP isn't really an option, so are there any other ideas for how to solve this?
