I get a NullPointerException (see end of message) when transforming the following file with fop-0.95. (fop-0.94 can handle this). <?xml version="1.0" encoding="utf-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"> <fo:layout-master-set> <fo:simple-page-master master-name="LetterPage" page-width="6in" page-height="3in"> <fo:region-body region-name="PageBody" margin="0.7in" background-color="rgb(245,245,245)"/> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="LetterPage" hyphenate="true"> <fo:flow flow-name="PageBody"> <fo:block font="12pt Arial"> <!-- the following line causes a NullPointerException, if hyphenate is true --> <fo:inline id="document.general.efficiently.dictionary"/> <!-- the following line is working fine --> Some <fo:inline font-weight="bold" color="red">inline text</fo:inline> formatting. </fo:block> </fo:flow> </fo:page-sequence> </fo:root> It only happens when hyphenation is set to true and if the <fo:inline> element does not contain any text (I came across this while transforming a docbook <anchor> tag with the the docbook-xsl stylesheets). I mark this bug as "critical" because it stops us from migrating to fop-0.95 (at least as long as there is not workaround available). ----------------------------------- java.lang.NullPointerException at org.apache.fop.layoutmgr.inline.InlineStackingLayoutManager.applyChanges(InlineStackingLayoutManager.java:350) at org.apache.fop.layoutmgr.inline.LineLayoutManager.findHyphenationPoints(LineLayoutManager.java:1480) at org.apache.fop.layoutmgr.inline.LineLayoutManager.findOptimalBreakingPoints(LineLayoutManager.java:950) at org.apache.fop.layoutmgr.inline.LineLayoutManager.createLineBreaks(LineLayoutManager.java:917) at org.apache.fop.layoutmgr.inline.LineLayoutManager.getNextKnuthElements(LineLayoutManager.java:607) at org.apache.fop.layoutmgr.BlockStackingLayoutManager.getNextKnuthElements(BlockStackingLayoutManager.java:294) at org.apache.fop.layoutmgr.BlockLayoutManager.getNextKnuthElements(BlockLayoutManager.java:116) at org.apache.fop.layoutmgr.FlowLayoutManager.getNextKnuthElements(FlowLayoutManager.java:107) at org.apache.fop.layoutmgr.PageBreaker.getNextKnuthElements(PageBreaker.java:145) at org.apache.fop.layoutmgr.AbstractBreaker.getNextBlockList(AbstractBreaker.java:552) at org.apache.fop.layoutmgr.PageBreaker.getNextBlockList(PageBreaker.java:137) at org.apache.fop.layoutmgr.AbstractBreaker.doLayout(AbstractBreaker.java:302) at org.apache.fop.layoutmgr.AbstractBreaker.doLayout(AbstractBreaker.java:264) at org.apache.fop.layoutmgr.PageSequenceLayoutManager.activateLayout(PageSequenceLayoutManager.java:106) at org.apache.fop.area.AreaTreeHandler.endPageSequence(AreaTreeHandler.java:234) at org.apache.fop.fo.pagination.PageSequence.endOfNode(PageSequence.java:123) at org.apache.fop.fo.FOTreeBuilder$MainFOHandler.endElement(FOTreeBuilder.java:340) at org.apache.fop.fo.FOTreeBuilder.endElement(FOTreeBuilder.java:169) at org.apache.xalan.transformer.TransformerIdentityImpl.endElement(TransformerIdentityImpl.java:1101) at org.apache.xerces.parsers.AbstractSAXParser.endElement(Unknown Source) at org.apache.xerces.xinclude.XIncludeHandler.endElement(Unknown Source) at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanEndElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.xalan.transformer.TransformerIdentityImpl.transform(TransformerIdentityImpl.java:484) at org.apache.fop.cli.InputHandler.transformTo(InputHandler.java:214) at org.apache.fop.cli.InputHandler.renderTo(InputHandler.java:125) at org.apache.fop.cli.Main.startFOP(Main.java:166) at org.apache.fop.cli.Main.main(Main.java:197)
Fixed in FOP Trunk. see: http://svn.apache.org/viewvc?rev=690382&view=rev Admitted, this is a very quick one, but still a fix... ;-) Thanks for reporting!
