Thanks for your reply, haste. I'll try to spawn them as a header with no worry. =)

Btw, I was going to spawn them as singles because I was failed to spawn party-target header.

oUF:Factory(function (self)
	self:SetActiveStyle('MyPartyTargetStyle')

	local partytarget = self:SpawnHeader(
		nil, nil, nil,
		'showParty', true, 'showPlayer', true,
		'point', 'TOP', 'yOffset', -36,
		'oUF-initialConfigFunction', [[
			self:SetAttribute('unitsuffix', 'target')
			self:SetWidth(84)
			self:SetHeight(24)
		]]
	)

	partytarget:SetPoint('LEFT', 30, 0)
	partytarget:Show()
end)

I think it was because of my fault but:
- These party-targets have not 'partytarget' as 'oUF-guessUnit' attribute.
- It seems 'enableTargetUpdate' function not works correctly. Though 'OnShow' update works.
(I mean when I have no target and then target someone, it's updated correctly. But when I chenge the target to the another one, it's not updated correctly)

Anyway, I'm sure I need farther testing. I'll post again when I find something useful to share.
