The impl in 5.4.3 is wrong. Essentially 5.4.3 introduced a regression, which I recall checking in a fix for in wonder, and I believe it's fixed in 5.4.3.1 :) like this:
if (parent is abstract) {
return my external name.
}
Which is just wrong. This was particularly a problem for Vertical Inheritance where various fields ought to have resolved to the parent entity's table (but didn't).
I've never tested horizontal inheritance but you can fix it by:
a) subclassing EOEntity and overriding primaryKeyRootName etc, or better
b) use Wonder and if Horizontal Inheritance is a problem, fix it there for all :)
