SetText on AceGUI multi line edit box results in no text after AFK

Edit: Sorry if this is in the wrong section, just noticed there's a Lua/XML Help section.

Hi.

I'm a few months into learning Lua and addon development.

My first addon allows players to customize each chat frame.

One of the features allows players to copy messages from a chat frame by duplicating them to an AceGUI multi line edit box when you hold control and left click on a chat tab.

I noticed that if I AFK for about 10 minutes and come back, sometimes no messages show up when I try to open the frame.

Lua Code:
  1. local AceGUI = LibStub("AceGUI-3.0")
  2.  
  3. --- @class Private
  4. local Private = select(2, ...)
  5.  
  6. --- @class CopyModule: AceModule
  7. local CopyModule = Private.Addon:NewModule("Copy")
  8.  
  9. --- @class CopyConstants
  10. local CopyConstants = Private.CopyConstants
  11.  
  12. --- @class ChatFrameUtils
  13. local ChatFrameUtils = Private.ChatFrameUtils
  14.  
  15. --- @class DatabaseUtils
  16. local DatabaseUtils = Private.DatabaseUtils
  17.  
  18. --- @class CopyState
  19. --- @field copyFrame table?
  20. --- @field multiLineEditBox table?
  21. --- @field text string?
  22. local state = {
  23.     copyFrame = nil,
  24.     multiLineEditBox = nil,
  25.     text = "",
  26. }
  27.  
  28. --- Configures the copy frame.
  29. local function configureCopyFrame(copyFrame)
  30.     copyFrame:SetTitle(CopyConstants.FRAME_TITLE)
  31.     copyFrame:SetWidth(CopyConstants.FRAME_WIDTH)
  32.     copyFrame:SetHeight(CopyConstants.FRAME_HEIGHT)
  33.     copyFrame:SetLayout(CopyConstants.FRAME_LAYOUT)
  34.     copyFrame.frame:EnableKeyboard(true)
  35.     copyFrame.frame:SetClampedToScreen(true)
  36.     copyFrame.frame:SetFrameStrata(CopyConstants.FRAME_STRATA)
  37.     copyFrame.frame:SetPropagateKeyboardInput(true)
  38. end
  39.  
  40. --- Creates the copy frame.
  41. local function createCopyFrame()
  42.     local copyFrame = AceGUI:Create("Frame")
  43.  
  44.     configureCopyFrame(copyFrame)
  45.  
  46.     return copyFrame
  47. end
  48.  
  49. --- Handles the text changing in the multi line edit box.
  50. local function onTextChangedCallback(widget)
  51.     local currentText = state.text
  52.     local cursorPosition = widget:GetCursorPosition()
  53.  
  54.     widget:SetText(currentText)
  55.     widget:SetCursorPosition(cursorPosition)
  56. end
  57.  
  58. --- Configures the multi line edit box.
  59. local function configureMultiLineEditBox(multiLineEditBox)
  60.     multiLineEditBox:DisableButton(true)
  61.     multiLineEditBox:SetLabel("")
  62.     multiLineEditBox:SetCallback("OnTextChanged", onTextChangedCallback)
  63. end
  64.  
  65. --- Creates the multi line edit box.
  66. local function createMultiLineEditBox()
  67.     local multiLineEditBox = AceGUI:Create("MultiLineEditBox")
  68.  
  69.     configureMultiLineEditBox(multiLineEditBox)
  70.  
  71.     return multiLineEditBox
  72. end
  73.  
  74. --- Updates the copy frame with the chat frame messages.
  75. --- @param chatFrame table
  76. local function updateCopyFrame(chatFrame)
  77.     state.text = table.concat(ChatFrameUtils:GetChatFrameMessages(chatFrame), "\n")
  78.     state.multiLineEditBox:SetText(state.text)
  79.  
  80.     -- To scroll to the bottom of the multi line edit box, we need to wait.
  81.     C_Timer.After(0, function()
  82.         state.multiLineEditBox:SetCursorPosition(#state.text)
  83.     end)
  84. end
  85.  
  86. --- Closes the copy frame.
  87. local function closeCopyFrame()
  88.     state.copyFrame:Hide()
  89.  
  90.     AceGUI:Release(state.copyFrame)
  91.  
  92.     state.copyFrame = nil
  93. end
  94.  
  95. --- Sets the escape key handler for a frame.
  96. local function setEscapeKeyHandler(frame, editBox)
  97.     frame:SetScript("OnKeyDown", function(self, key)
  98.         if key ~= "ESCAPE" then
  99.             self:SetPropagateKeyboardInput(true)
  100.  
  101.             return
  102.         end
  103.  
  104.         closeCopyFrame()
  105.  
  106.         self:SetPropagateKeyboardInput(false)
  107.     end)
  108. end
  109.  
  110. --- Initializes the copy frame.
  111. local function initializeCopyFrame()
  112.     local copyFrame = createCopyFrame()
  113.     local multiLineEditBox = createMultiLineEditBox()
  114.  
  115.     copyFrame:AddChild(multiLineEditBox)
  116.  
  117.     setEscapeKeyHandler(copyFrame.frame, multiLineEditBox.editBox)
  118.  
  119.     state.copyFrame = copyFrame
  120.     state.multiLineEditBox = multiLineEditBox
  121.     state.text = ""
  122. end
  123.  
  124. --- Shows the copy frame.
  125. --- @param chatFrame table
  126. function CopyModule:ShowCopyFrame(chatFrame)
  127.     if not state.copyFrame then
  128.         initializeCopyFrame()
  129.     end
  130.  
  131.     updateCopyFrame(chatFrame)
  132.  
  133.     state.copyFrame:Show()
  134.     state.copyFrame.frame:SetPropagateKeyboardInput(true)
  135. end

I have tried to debug the problem as shown below. I was able to reproduce the issue of the messages not showing up in the multi line edit box, but they would appear in ChatFrame4 and ChatFrame5.

Lua Code:
  1. --- Updates the copy frame with the chat frame messages.
  2. --- @param chatFrame table
  3. local function updateCopyFrame(chatFrame)
  4.     state.text = table.concat(ChatFrameUtils:GetChatFrameMessages(chatFrame), "\n")
  5.     ChatFrame5:AddMessage(state.text)
  6.     state.multiLineEditBox:SetText(state.text)
  7.  
  8.     for _, msg in ipairs(ChatFrameUtils:GetChatFrameMessages(chatFrame)) do
  9.         ChatFrame4:AddMessage(msg)
  10.     end
  11.  
  12.     C_Timer.After(2, function()
  13.         state.multiLineEditBox:SetText(state.text)
  14.     end)
  15.  
  16.     -- To scroll to the bottom of the multi line edit box, we need to wait.
  17.     C_Timer.After(4, function()
  18.         state.multiLineEditBox:SetCursorPosition(#state.text)
  19.     end)
  20. end

My code is on GitHub as well so it might be easier to look at here: https://github.com/drzewieckinichola...dules/Copy.lua

The files we're probably interested in are Modules/Copy.lua, Hooks/ChatFrame.lua, and I guess Utils/ChatFrame.lua, but I'm assuming the problem is in Modules/Copy.lua.

Does anybody have any idea what I'm doing wrong?

Thanks in advance!
