How to fill a dropdownbutton with the guild roster

[loopylama]

i have this:

    PlayerDropDownMenu = CreateFrame("Frame", "PlayerDropDownMenu", Frame, "UIDropDownMenuTemplate"); 
    PlayerDropDownMenu:SetPoint("Left",Frame, 120, -198)
    UIDropDownMenu_SetWidth(80, PlayerDropDownMenu)
    UIDropDownMenu_SetButtonWidth(20, PlayerDropDownMenu)
    UIDropDownMenu_Initialize(PlayerDropDownMenu, PlayerDropDownMenu_Initialise)

function PlayerDropDownMenu_Initialise() 
	level = 1
    local info = UIDropDownMenu_CreateInfo(); 
	for i=0,GetNumGuildMembers(true) do
		name, rank, rankIndex, level, class, zone, note, officernote, online, status = GetGuildRosterInfo(i)
		info.text = name
		info.value = name
		info.func = function() PlayerDropDownMenu_OnClick() end
		info.owner = this:GetParent()
		info.checked = nil; 
		UIDropDownMenu_AddButton(info, level)
	end
end

static loading works, only the guild roster wont work.

Anyone has an idea what i might do wrong?

Do the index for GetGuildRosterInfo() really starts with 0? Not with 1?

function PlayerDropDownMenu_OnClick()
	UIDropDownMenu_SetSelectedValue(this.owner, this.value)
end

Move

function PlayerDropDownMenu_Initialise()...end

before

UIDropDownMenu_Initialize(PlayerDropDownMenu, PlayerDropDownMenu_Initialise)

It's nil otherwise.

doesnt solve the problem. Static loading works. But when i try to load the guild roster nothing appears

No error messages? oO

No nothing, the dropdownbutton just remains empty while the static loaded one above it got filled

If I add the code from you first post to an empty addon and move PlayerDropDownMenu_Initialise() before UIDropDownMenu_Initialize() I get the error message "... attempt to index global 'this' (a nil value)".

This means there are three possible options:
1. There's other code you didn't show up to now
2. The shown code isn't up-to-date
3. Your lua error messages are deactivated

Please choose and fix.

1. theres is other code which has nothing to do with this subject
2. that code is currently in my project
3. I use !swatter to grab my bugs.

And yes i got that error as well if i swap the positions

when does this run? are you confirming that the guild roster has loaded from the server first (after "GUILD_ROSTER_UPDATE")?

got it to work. But now i cant filter the "veteran alt"s out. this is the code

function PlayerDropDownMenu_Initialise() 
	level = 1
    local info = UIDropDownMenu_CreateInfo(); 
	for i=1,GetNumGuildMembers(true) do
		local name = GetGuildRosterInfo(i)
		local rank = GetGuildRosterInfo(i)
		if (rank=="Veteran Alt") then
			info.text = "------------------"
			info.value = "------------------"
			info.func = function() PlayerDropDownMenu_OnClick() end
			info.owner = this:GetParent()
			info.checked = nil; 
			UIDropDownMenu_AddButton(info, level)
		else
			info.text = name
			info.value = name
			info.func = function() PlayerDropDownMenu_OnClick() end
			info.owner = this:GetParent()
			info.checked = nil; 
			UIDropDownMenu_AddButton(info, level)
		end
	end
end

local name, rank = GetGuildRosterInfo(i)

eliminate the other GetGuildRosterInfo(index) call.

Edit: Better yet, call the function properly with all args :

local name, rank, rankIndex, level, class, zone, note, officernote, online, status = GetGuildRosterInfo(i);

and do an : if online then...end before adding the buttons in your loop. If you are only interested in the name and rank you can also it omit the other args :

local name, rank, _, _, _, _, _, _, online, _ = GetGuildRosterInfo(i);

should be:

local name, rank = GetGuildRosterInfo(i)

now i have this:

function PlayerDropDownMenu_Initialise() 
	level = 1
    local info = UIDropDownMenu_CreateInfo(); 
	for i=1,GetNumGuildMembers(true) do
		local name, rank, rankIndex, level, class, zone, note, officernote, online, status = GetGuildRosterInfo(i)
		if (rank~="Member Alt") then
			info.text = name
			info.value = name
			info.func = function() PlayerDropDownMenu_OnClick() end
			info.owner = this:GetParent()
			info.checked = nil;
			UIDropDownMenu_AddButton(info, level) 
		end	
	end
end

error:
