[sword-devel] Prevent setKey from 'Leaking' into overlapping chapters/books

[Alex S]

Troy, Thanks so much for the reply.

I added parser.setAutoNormalize(false) before the result = parser.ParseVerseList(....) in verserangeparser.cpp. Now when I run the program with an invalid reference like jn22:1, I don't get any output but it looks like it errors out, even if I have some valid references in the list, such as jn3:16,jn22:1. Could you give me a few pointers on how to skip over the bad values in the for loops and continue execution wit the valid references? 

Regards
Alex
