I am using MySQL and the DECIMAL data type. That could explain the
difference.

Interesting, I'm not seeing this behavior at all in 5.2.3. I have a
BigDecimal (10, 2) and am using the formatter "0.##" and all seems
fine. Whole number display correctly as "3" and decimals will
correctly round to 2 digits like "3.15" for example.

Yes, setting the ValueType to 'B' works and takes care of the
ClassCastException, but the problem I'm having is that the scale of
the BigDecimal isn't being set correctly. So, for example, if I
have a whole number value like 3, the value that's returned comes
out as 3.000000000. The default behavior of BigDecimal is to chop
off those extra digits after the decimal. So somewhere in the
instantiation of the BigDecimal, setScale() is being called.
Unfortunately, just setting the scale in EOModeler doesn't work.
In 5.2.2, the solution was to set the ValueType to 'd', which would
create a BigDecimal, but the scale would be set properly. This
doesn't work in 5.2.3.
The reason why this is a problem is mainly for display purposes. If
I have a value that uses a formatter of "0.##" because I _sometimes_
need to show the digits after the decimal, it will now always show
the zeros. In 5.2.2, it would show "3" with a formatter of "0.##",
but now that the scale is being set too high, it always shows "3.00"
I can't remember, but I think that this also causes a problem with
comparing 2 BigDecimals. Because 3 != 3.000000000. I'll have to
double check on this though.

This behavior is again confirmed. I installed the 5.2.3 update on
my test development box and found this problem.
This appears [SO FAR] to be a bug FIX not a new bug. I did not
have the "B" value type set for my BigDecimal's in my model. WO
5.2.3 now throws the class cast exception, as it probably should
have in 5.2.2. I could be wrong about this. However, adding the
correct ValueType ("B" in this case) fixes the problem.

I upgraded to WO 5.2.3 today on my Mac OS x 10.3.3 development
machine.
I get ClassCastExceptions exceptions for (at least some)
BigDecimals. I don't have Booleans.
I also see this behavior, after upgrading dev to 5.2.3.
I've got an EO with an attribute modeled as NSDecimalNumber, which
maps to a FLOAT column in the DB. The code output by EOModeler
casts this attribute to a BigDecimal, which throws the exception.
Worked in 5.2.2.
