htmllayout.cpp (line 128) has a bug when checking if ndc is null. Instead of:
if(event->getNDC().length() != 0)
it should be:
While using the HTMLLayout it's easily detected as 'NDC: null' appears.
I've just downloaded the last svn version, so I think the problem hasn't been solved jet.
Replacing line 128 and adding the ndc header:
are the only actiones needed to fix this bug; I've tested it and it works correctly – thou I only tested it without ndc.
