Buffs and Applying Modifiers not working ?

Problem - modifier "Bonus" applied to attacking unit and target unit.
The target unit has an initial armor value of 4. The attacking unit,
in this case the rifleman has baseDamage of 50. The modifier is never
applied to the damage for the attacker. The modifier is never applied
to the armor of the target. buffs.cs, rifleman.cs and console.log
excerpts follow.

Is this a bug ? I dropped back to the base code (away from modifications I am making) to test this.

buffs.cs
---------
datablock RTSUnitModifierData(Bonus)
{
baseDamage = 1.5;
attackDelay = 0.75;
armor = 2.0;
moveSpeed = 1.5;
};

rifleman.cs
-----------
function riflemanBlock::onAttack(%this, %attacker, %target)
{
%damage = %attacker.getDataBlock().baseDamage;
echo("riflemanBlock onAttack damage1: " @ %damage); <--------------

if(%attacker.getNetModifier().baseDamage)
%damage *= %attacker.getNetModifier().baseDamage;

echo("riflemanBlock onAttack damage2: " @ %damage);<--------------

%armor = %target.getDataBlock().armor;
echo("riflemanBlock onAttack armor1: " @ %armor);<--------------

if(%target.getNetModifier().armor)
%armor *= %target.getNetModifier().armor;

echo("riflemanBlock onAttack armor2: " @ %armor);<--------------

console.log
-----------
