Hi,

Just for reference, is that my fault or WO fault? To be quite
frank, I cannot find in specifications the exact API contract for

numeric value, nonzero equals true), but quite clearly they do not :(
The Java language specification does not allow conversion of non-
boolean primitives to boolean primitives. The java.lang.Number API
is consistent with this: it does not have a boolean-export method.
In short: there is no contract for this.
What on earth has Java and its contracts to do with this?!?
WebObjects are no Java; it's a language-independent framework,
actually designed for Objective C. The assumption that its number-to-
boolean translation is C-like is thus well-founded and very reasonable
(of course, unless _its_ documentation says otherwise).
The problem is "how exactly WebObjects should translate numeric
objects to boolean in .wod bindins". That's what should be somewhere
in the WO documentation (defintely not Java one), but I can't find it
there :(
Anyway, this problem is pretty unimportant -- it's just an interesting
question, but it's of no real consequence. The really important
question is

condition is a BigDecimal, and append ".signum" to the condition?
(The project's Xcode, so I can use its regexp search&replace, or of
course some external sed-based script... but I see no way to find
the BigDecimal conditions only :( )
:)
Thanks and best,
