How to check unit state

[Peacegetter]

Hi,

I'm having trouble finding the right condition, that checks the following:
If a control tower upgrades to a canon tower for example, and he gets killed while upgrading and just while upgrading i want to let certain actions happen. But either im to stupid or there is no potion to check that in the editor (what i don't belive). So I tried different ways, for example making a dummy unit while the construction is progressing etc.. but it doesent work the way i planned.

So is there a way to trigger it like this?

TowerOutpostgold
Events
Unit - A unit Dies
Conditions
(Unit-type of (Triggering unit)) Equal to (==) Canon Tower
[here is the missing condition that checks if the tower is still in construction/upgrading]
Actions
Player - Add 6000 to (Owner of (Triggering unit)) Aktuelles Gold

Thanks for any help

EDIT: Okay i just found another solution for myself, just setting the upgrade status to 100 when units life is at 5% but i have another question, is there any way to remove a non learned ability from a unit?

Test this, this should work ;b
First trigger, pick them first

Pick them first Events Unit - A unit Begins an upgrade Conditions Actions Unit Group - Add (Triggering unit) to Unit_Group

Second trigger, remove them from the group

Cancel or Finish Events Unit - A unit Cancels construction Unit - A unit Finishes an upgrade Conditions Actions Unit Group - Remove (Triggering unit) from Unit_Group

Third trigger, add your actions here

Tower Events Unit - A unit Dies Conditions ((Triggering unit) is in Unit_Group) Equal to True <-- Find it in Boolean Actions Your actions here......
