Bug #: 52763
Summary: When a marker contains list-block FOP crashes with NPE
Product: Fop
Version: 1.1dev
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: normal
Priority: P2
Component: page-master/layout
AssignedTo: fop-dev@xmlgraphics.apache.org
ReportedBy: i...@siberlogic.com
Classification: Unclassified
The BlockLayoutManager throws an NPE in the line
FontTriplet[] fontkeys = getBlockFO().getCommonFont().getFontState(fi);
in the initialize() method when the marker contains fo:block/fo:list-block:
<fo:flow flow-name="xsl-region-body">
<fo:block><fo:marker
marker-class-name="message"><fo:block>
WARNING: Page sequence contains: <fo:page-number-citation
ref-id="end-seq1"/> pages.
</fo:block>
<fo:block>
<fo:list-block><fo:list-item><fo:list-item-label><fo:block font-weight="bold"
color="black">NOTE:</fo:block>
</fo:list-item-label>
<fo:list-item-body start-indent="0.5in"><fo:block text-align="left"
color="black">This manual supersedes TM PUBNAME-00 dated 15 December 2004. Zero
in the "Change No." column indicates an original page or work
package.</fo:block>
</fo:list-item-body>
</fo:list-item>
</fo:list-block>
</fo:block>
</fo:marker>
</fo:block>
The reason is that the layout manager tries to set itself up using the
properties of the block. However the block is not bound to the property list,
because the inMarker() function returns true for such a block:
FObj.java
public void processNode(String elementName, Locator locator,
Attributes attlist, PropertyList pList)
throws FOPException {
setLocator(locator);
pList.addAttributesToList(attlist);
if (!inMarker()
|| "marker".equals(elementName)) {
pList.setWritingMode();
bind(pList);
}
Thus the block contains all empty fields and attempt to retrieve them causes an
NPE.
Don't know if it has been resolved in FOP 1.1
