Behavior Ids

[Sven Meier]

Hi,

I don't understand Behaviors#internalAdd(Behavior):
    private void internalAdd(final Behavior behavior)
    {
        component.data_add(behavior);
        if (behavior.getStatelessHint(component))
        {
            getBehaviorId(behavior);
        }
    }

Why does it register the behavior for an id if its stateless? Shouldn't 
that be done in the opposite? Why isn't it done lazily when needed only?

Note that the condition has flipped back and forth a few times in the 
commit history. Now each simple AttributeModifier is put into the 
BehaviorIdList, although the id is never used for it.

@marting + igor: Any thoughts?
