weird cache like behavior related to typecasting
Reported by jack dempsey (jackdempsey) | November 11th, 2008 @ 04:15 PM
Strange behavior--dkubb has suggested it might be grabbing the object from the IdentityMap lookup (which may not be needed). Anyway, wanted to document this here.

I believe in this case Property#typecast has an incorrect approach to typecasting integers.
For Integer properties should probably use a Regexp to ensure the String is "like a number", and then apply String#to_i on it, as I think most people would expect.
I will make sure this is resolved in dkubb/dm-core.

Attached is a script that duplicates the code in the gist, but does not have the same problem with cached results being returned.
However, it does show one of the original problems I found, which was that the Property#typecast method doesn't properly check the value to see if it remotely resembles a number. In this case it does not, so it shouldn't execute a query where the "is is NULL" at all. It should just return nil directly.

Just committed a fix to dkubb/dm-core that resolves this specific issue:
