NullPointerException if a language highlighting is not available #26

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The docbkx plugin crashes with a NullPointerException if a language
highlighting is not available (for instance, bash) when defining the
language attribute of a programlisting element.

What steps will reproduce the problem?
1. put the following piece of code in a docbook xml file :
<programlisting language="bash">export APP_HOME=/some/path</programlisting>
2. activate the hightlighting in your pom :
<highlightSource>true</highlightSource>
3. run the generation

The expected output is as following :
java.lang.NullPointerException

Hi Christophe and thank you for your support.

I think the bug you are mentioning is not in our side, it is on xslthl side. We 
are
based on xslth-1.3.jar
The only thing that can be done is to update to latest xslthl version (maybe it 
will
solve the problem) but it means that we have to move to docbook xsl 1.74+

As we do not have yet moved latest docbook xsl versions I think we cannot 
resolve
this minor bug.
Maybe you can also write an xsl layer to check that if you are really in need 
of this
feature?
