About tdf#92720: Report fails to open with Charts in a Report

[julien2412]

Hello,

Giving a try to tdf#92720, I retrieved a bt which shows a pb with
XML_NAMESPACE_LO_EXT
Indeed when search XML_P ("p" element), we don't find it in
SvXMLNamespaceMap::GetQNameByKey (see
http://opengrok.libreoffice.org/xref/core/xmloff/source/core/nmspmap.cxx#238)
because aNameMap doesn't contain XML_NAMESPACE_LO_EXT.

Searching a bit, I noticed that in xmloff/source/core/xmlexp.cxx, this
namespace was added only if :

getExportFlags() &
(SvXMLExportFlags::STYLES|SvXMLExportFlags::AUTOSTYLES|SvXMLExportFlags::MASTERSTYLES|SvXMLExportFlags::CONTENT)
(see
http://opengrok.libreoffice.org/xref/core/xmloff/source/core/xmlexp.cxx#340)
+
getDefaultVersion() > SvtSaveOptions::ODFVER_012
(see
http://opengrok.libreoffice.org/xref/core/xmloff/source/core/xmlexp.cxx#355)
If I move out the second if from the first if, I got no crash but a Java
stack trace with Pentaho complaining it doesn't know XML_NAMESPACE_LO_EXT

So finally, I thought about this patch to workaround this and prevent from
the crash:

(like
http://cgit.freedesktop.org/libreoffice/core/commit/?id=6acc6c011d3afd6834efeee1b2efe43652a86f2e
which introduced XML_NAMESPACE_LO_EXT - thanks to Matthew Francis for having
pinpointed it in bugtracker - in this part and which sometimes doesn't use
eExtensionNS parameter)

Any thoughts?

Julien
