[TM4J-users] Problems with paramaterized prepared queries

[Bret C. <bre...@ya...>]

Kal,

I would have been tempted to think what I've just
found is a bug, but my past experiences have shown
that the only bugs to be encountered are
- the flu that I can't seem to permanently fight off
- me  - bugging you about something that either turns
out not to be a problem or that has an easy solution
in retrospect. ;>

Nevertheless, if you could take a look at the
attached, it would be appreciated.
