Attachments with Alternate animations?

[madmuffin]

I have model who's stand animation is of it as a floating item, and it's alternate animation is of it as an attachment. My problem is, I can't get it to appear in a unit's had in the alternate pose. I'm doing this with abilities on items, not with triggers. I set the animation names on the item to be Alternate, but it didn't seem to have an effect on the model. If anyone can help it, it would be appreciated.
