[rules-users] Fully qualified name for generated classes

[Lance Leverich]

The issue isn't that Foo cannot be resolved, as it was imported into both
packages from the Global Area. The packages compile just fine. I believe
what might be happening, though, is that each package is creating its own
version of Foo.
For example, am I experiencing something like...
    com.mypkg.a generates a class with a fully qualified name of
drools.com.mypkg.a.Foo
    com.mypkg.b generates a class with a fully qualified name of
drools.com.mypkg.b.Foo
?

If this is the case, is there someway within Guvnor to refer to a
particular version? I'm beginning to think that my best option might be to
create a POJO and import it. At least that way, I can make sure I know the
fully qualified (i.e. canonical) class name.
