Re: Morgana and Schematron configuration question

Hi David,
The NullPointer comes from the compilation of Schematron to XSLT, so I would like to see the Schematron document in order to see, what went wrong there.
Is there a change you mail me the "adj-paradigms-in-dictionary.sch"?
Thanks,
Achim

I was confused, when I first began using Morgana, by how Morgana expects options to follow the name of the file being processed, e.g., the correct Morgana.sh filename.xpl -xslt-connector=Saxon10 rather than the incorrect Morgana.sh -xslt-connector=Saxon10 filename.xpl. I had initially expected the latter because so many other applications and commands put command-line options (with leading "-" characters) before the target of the operation. Having learned that Morgana wants the filename before the options, when I read the instruction to put the -config option first, I misunderstood it as "the first option, but all options still follow the filename". Allowing options to appear in any order would be helpful, but I understand that parsing command-line options can be a time sink, and that the effort that would require might better be applied to functionality and features.
