[JW Lua] Strange error message

[Charles O. Lawrence]

As it turned out in this particular case, I was mistakenly trying to assign
a boolean value to a class object property that was supposed to be an
integer.  The error message was completely baffling since there was no
arguments involved, only an assignment.  It must be an "internal to the PDK"
run time error that is being raised, since Lua is not a typed language
whereas C++ (PDK) is.  Does that make sense?  Also, there was no red "spot"
flagged on the JW Lua source, nor a line number given.  I was able to find
the offending assignment since the error began occurring after I had added a
few more lines of Lua code, so I knew where to look.  If it used to work and
it doesn't anymore, then something you just did must have caused the error.
Old programmers adage!

Charles,

My guess would be that it's one of the JW Lua iterators (each, eachentry,
eachentrysaved, etc) that's reports it, even though I can't create a
scenario that reproduces it.
