Upgraded buildings vs Sold Units

Right, I'm having this wee tiny little problem here. I want to have a generic start-building, something like a Circle of Power, wich you upgrade to a number of different buildings. Inspired by EA's BfME, althou different.
Anyway, so I want to upgrade to, say, a Barrack. Not an usual barrack, thou; no, I want a barrack that sells units, not training them.
So I fix three units in the Object Editor - the Circle, the Barrack and the Unit. Say it's a footman or whatever.
The Circle I make upgradeable to a Barrack. So far so good.
In the Barrack, I add the unit to the Sold Units-field.
And the unit I simply edit so it is... buyable. Bleh, edit cooldowns and such.

Now, now. So I place a Circle in the map, and run the map. I upgrade the Circle. I get, indeed, a Barrack - but the barrack can't sell anything! The portrait/icons won't even appear!
So I change and just upgrade to an ordinary Mercenary Camp.
No.

I then change so that the unit I want sold, is instead trained. Then it shows up.

The conclusion: if you upgrade a building to a building wich sells units, the units won't appear.



NOW HOW THE "¤)&¤&()/¤&() do I come over this obstacle? Preferably without the use of triggers, please. It gets annoying after a while when you have to do it with aaall buildings, practically.

With triggers this can be fixed very easily. Without triggers it think what you have to do is add the units AGAIN to the barracks cause when a building is upgraded, it becomes a completely different unit i believe. Just ask if you want teh trigger solution.

Actually, the problem is that units that are upgraded from other units can't have any abilities that the units below them didn't have. Try giving the CoP a Sells Units ability like your Barracks. Also, just make sure that your Barracks has all the same unit abilities as a mercenary camp.

If nothing else works, you can make a tiny trigger that replaces the barracks with a barracks when it's finished constructing. Since it's no longer a barracks that was upgraded from a prior unit, it can have any abilities you want.

Aye. Well it seems that it was, in fact, so. I think I'll stick to the replacing-thingy; seems simple 'nuff.

Thanks lads. Been helpfull.

Apart from the fact it won't work...

You need to add the abilities that allow a building to sell things.
