blank frames on login

[drakken2015]

It happens about 50% of the time. When I sign into a toon I get the background image of the UI but nothing else..

Strange thing is if I hit Enter and type "/reloadui" it reloads and looks fine.

I've noticed that as well sometimes. I'm sure its my case of wiping the wtf files but this time I made a point of logging into each character without nUI before installing nUI and logging in so not sure whats happening there.

I actually think this problem is related to the key binding problem I'm trying to run down. There appears to be a "state" where the player is logging in but WoW has not yet initialized everything yet.

In the case you're referring to here, the problem is that the saved variables have not really been loaded when the "VARIABLES_LOADED" event fires. I've seen this myself. The "nUI_Options" variable is nil when this happens and that blows up the UI.

When you reload, because nUI_Options is written as nil on the log out, it causes nUI to reinitialize the saved variables.

It's a real mess and the symptoms are almost identical to the key binding problem with the exception that it is saved variables rather than binding data that is affected.

Ah, kinda makes sense.

But when do you initialise the nUI_Options ?

All my addons initialise the saved variables with the default values outside of the functions themselves and thus before the saved variables are loaded and replace these defaults. I've never had a problem like this with that data that way.

Say for example:

MyAddon.lua in wtf folder
SVData["Table1"] = {
Item1 = "SavedVariable"
};

MyAddon_SVData.lua
SVData["Table1"] = {};
SVData["Table1"].Item1 = "SomeTextHere";
etc

MyAddon.lua - loaded after MyAddon_SVData.lua is processed
function OnEvent()
Event = PlayerLogin
SVData["Table1"].Item1 would = "SomeTextHere"
Event = LoadVariables
SVData["Table1"].Item1 would = "SavedVariable"
end

This way the addon doesn't bomb out but will use the default values until the saved variables are loaded into memory. It's the way I have always dealt with saved variables and I have yet to have any of my data tables show up as nil ... *touches wood*

The nUI_Options variable is initialized when the Lua code is loaded by the UI. But when the VARIABLES_LOADED event fires, the initialized values have been overloaded by the "failed" saved variables read and that's what causes the blow-up.

[spiel2001]

If you are getting a blank screen at login, or you are getting the "attempt to perform arithmetic on a nil value" error in line 214 of nUI_ChatFrame.lua then try saving the attached file in [ Interface > AddOns > nUI > Integration ] and let me know if it fixes the problem.

ah gotcha, annoying blighter

I've been seeing this issue roughly half the time here, can't enter anything into the chatframe, so I remedy the problem by logging out and back in. Bags are in place, chat frame buttons appear usually in the right infopanel, sometimes in the left.

Hopefully, the below with aid in shedding a bit of light on things:

You can actually still type as if the chat frame is there. Just remember what you're typing and type /nui rl. Saves logging out and in again.
