Changes to BuffFrame.lua ?

[Enxo]

Hi !


I just tryed my pre 3.3 Addon Proggy and ran into this Error:

Message: Interface\FrameXML\BuffFrame.lua:184: attempt to index field 'duration' (a nil value)
Time: 05/09/10 17:58:06

consolidatedBuffs = <table> {
}

It worked perfectly fine before but i didnt use it for some time.
It uses alot of the BuffFrame.lua code pre 3.3.

Anyone got a clue why the error is in the BuffFrame.lua, since i didnt edit it for shure

how are you referencing duration ? If at all.

Looking at the buffframe.lua and xml files buff.duration refers to the fontstring holding the duration timer. Here are the two files with the relative segments highlighted. All I can think of is that there are some changes based on the consolidated buffs other than that I can't see anything that would make buff.duration not exist within buffframe.xml/lua.

	<Button name="AuraButtonTemplate" virtual="true">
		<Size x="30" y="30"/>
		<Layers>
			<Layer level="BACKGROUND">
				<Texture name="$parentIcon" nonBlocking="true"/>
				<FontString name="$parentCount" inherits="NumberFontNormal" parentKey="count">
					<Anchors>
						<Anchor point="BOTTOMRIGHT">
							<Offset>
								<AbsDimension x="-2" y="2"/>
							</Offset>
						</Anchor>
					</Anchors>
				</FontString>
				<FontString name="$parentDuration" inherits="GameFontNormalSmall" hidden="true" parentKey="duration">
					<Anchors>
						<Anchor point="TOP" relativePoint="BOTTOM" />
					</Anchors>
				</FontString>
			</Layer>
		</Layers>
		<Scripts>
			<OnEnter>
				GameTooltip:SetOwner(self, "ANCHOR_BOTTOMLEFT");
				GameTooltip:SetFrameLevel(self:GetFrameLevel() + 2);
				GameTooltip:SetUnitAura(PlayerFrame.unit, self:GetID(), self.filter);
			</OnEnter>
			<OnLeave>
				GameTooltip:Hide();
			</OnLeave>
		</Scripts>
	</Button>

		if ( duration > 0 and expirationTime ) then
			if ( SHOW_BUFF_DURATIONS == "1" ) then
				buff.duration:Show();
			else
				buff.duration:Hide();
			end

			if ( not buff.timeLeft ) then
				buff.timeLeft = expirationTime - GetTime();
				buff:SetScript("OnUpdate", AuraButton_OnUpdate);
			else
				buff.timeLeft = expirationTime - GetTime();
			end
		else
			buff.duration:Hide();
			if ( buff.timeLeft ) then
				buff:SetScript("OnUpdate", nil);
			end
			buff.timeLeft = nil;
		end

First of all thank you for your quick answer


The problem is that its been some time since i wrote it and I am still trying to get behind everything

The funny thing is that everythings working as intendet, besides that error. It looks like the error has no visual impact on anything.

It should also be mentioned that it only accours after the hiden Frame gets shown() again.

To answer your question, im using the buffFrame.lua code but without interfering with its variables (thats what i thougth )

Instead of "buff.duration" i am using a local called "buffduration". I am "stealing" the "buff.duration" data from buffFrame.lua by:

local buffduration = _G[buffName.."Duration"];

The term "buff.duration" does not exist anywhere in my code and is i said the addon works fine and the Blizz buffs als well.
Thats why im so confused

EDIT: Both lines refered in the error use Show() also:

Interface\FrameXML\BuffFrame.lua:184: in function `AuraButton_Update'
[string "*:OnShow"]:2: in function <[string "*:OnShow"]:1>
[C]: in function `Show'

Could the funktion Show() make any problems?
