[rules-users] You must see this, guys...new bug? defining rules saturday night made me mad?

[Edson Tirelli]

   Need to see the full test case to be able to understand if it is a bug or
not, because the expression in the LHS is using the ShadowProxy, while the
one in the RHS is not... so, it may be a bug or it may not... depends when
and how you are setting the upronto field.
