Hi,
I use getElementsByTagNameNS method in assets.xsp file.
Like that :
try{ ...
subject =
metaDoc.getElementsByTagNameNS("http://purl.org/dc/elements/1.1/","subject";).item(0).getChildNodes().item(0).getNodeValue();
} catch ....
But if <dc:subject/> element in .meta file is empty (like
<dc:subject></dc:subject>) I obtain this error :
ServerPagesGenerator.generate()
cause: java.lang.NullPointerException
Original Exception: java.lang.NullPointerException
