#27 TDD hash converts scalar values to string
Hello,
I got an error when doing the comparizion in FTL, but
once I change the data source from TDD to CSV, and
specified prices with 'n', it works fine.
Not sure it is a bug or not, but i think FMPP is
important to test and debug the FTL design, so i
report it.
Best Regards
Ray Linn

What a ugly fat bug you have found! The problem is with the
TDD parser, that forces the type of every values to string
that are inside {...}. BTW, the outermost {...} is redundant
in your TDD file example; if you remove that, then it will
work. Still, it's a bug, and it can still affect you if
later you will have a key-value pair where the value is a
hash. So here is the hotfix (replace fmpp.jar with this):
http://fmpp.sourceforge.net/qfix/fmpp.jar
This fix will be included in FMPP 0.9.12. Time to do that
release...
