I've been able to get upgrades to work beautifully, but for some reason this one won't budge. Here is the relevant code:

CommandButton Command_PurchaseUpgradeISD1
  Command          = OBJECT_UPGRADE
  Upgrade          = Upgrade_ImperatorISD1
  Options	   = OK_FOR_MULTI_SELECT CANCELABLE
  TextLabel        = CONTROLBAR:UpgradeISD1
  ButtonImage      = UIISD1
  ButtonBorderType = UPGRADE
  DescriptLabel    = CONTROLBAR:ToolTipUpgradeISD1
  InPalantir	   = Yes
End

This is the button for the upgrade that is in the units commandset which references to:

Upgrade Upgrade_ImperatorISD1
	DisplayName       = UPGRADE:ISD1
	Type              = OBJECT
	Tooltip		= TOOLTIP:ISD1
	BuildCost		= 5
	BuildTime		= 10.0
	ResearchSound	= UpgradeFlamingArrows
	UpgradeFX		= FX:GenericBuildingUpgrade
End

And finally the code within the units ini file:

;;;;;;;;;;;;;;;;;;;;;Class I Upgrade;;;;;;;;;;;;;;;;;;;;;;;;;;;;

 	Behavior = SubObjectsUpgrade ModuleTag_ShowISD1 
		TriggeredBy	= Upgrade_ImperatorISD1
		ShowSubObjects	= QUADL QUADR ISD1
	End

	Behavior = WeaponSetUpgrade WeaponSetUpgradeModuleTag
		TriggeredBy = Upgrade_ImperatorISD1
	End

And heres a bit that hides the subobjects so the upgrade can show them.

	Behavior = SubObjectsUpgrade ModuleTag_HideUpgrades
		TriggeredBy	= Upgrade_StructureLevel1
		HideSubObjects	= QUADL QUADR ISD1 ISD2
	End

Ok, the problem is the upgrade button is greyed out. Here are things i have tried:

- Changed it from an OBJECT upgrade to a PLAYER upgrade. This made the button clickable, but you could click it indefinitely and nothing would happen.

- I tried each of the behavior modules seperately, but no combination worked, and without any modules the button of course says "this unit cannot recieve this upgrade".

I've tried numerous other things, but nothing has worked. What could possibly be wrong? Did I forget something?
