### Summary When using a Pop-Up Dialog Device in Verse, the RespondingButtonEvent returns an agent and index. Buttons 1-6 use zero-based indexing and buttons 7-12 use one-based indexing, which is weird and inconsistent, but is best left unpatched and made clear that the bug exists so existing code doesn’t break. ### Please select what you are reporting on: Verse ### What Type of Bug are you experiencing? Verse ### Steps to Reproduce Create a new project. Add a Pop-Up Dialog Device with 12 buttons, a Button Device whose Interact Event is linked to the Pop-Up Dialog’s Show function, and a Verse device. Paste the following code into the Verse device: ``` using { /Fortnite.com/Devices } using { /Verse.org/Simulation } using { /UnrealEngine.com/Temporary/Diagnostics } popup_dialog_watcher := class(creative_device): @editable Popup : popup_dialog_device = popup_dialog_device{} OnBegin():void= Popup.RespondingButtonEvent.Subscribe(PrintPopup) PrintPopup(Agent : agent, Index : int) : void = Print("{Index}") ``` Reference the Pop-Up Dialog in the Verse device and start the game while connected to a session. ### Expected Result When the player in the game client presses a button, the zero-based index of that button should be printed on screen: | Button Pressed | Index Passed Through RespondingButtonEvent | | --- | --- | | Button 1 | 0 | | Button 2 | 1 | | Button 3 | 2 | | Button 4 | 3 | | Button 5 | 4 | | Button 6 | 5 | | Button 7 | 6 | | Button 8 | 7 | | Button 9 | 8 | | Button 10 | 9 | | Button 11 | 10 | | Button 12 | 11 | ### Observed Result When the player in the game client presses a button 7-12, the one-based index of that button is printed on screen. | Button Pressed | Index Passed Through RespondingButtonEvent | | --- | --- | | Button 1 | 0 | | Button 2 | 1 | | Button 3 | 2 | | Button 4 | 3 | | Button 5 | 4 | | Button 6 | 5 | | Button 7 | 7 | | Button 8 | 8 | | Button 9 | 9 | | Button 10 | 10 | | Button 11 | 11 | | Button 12 | 12 | ### Platform(s) I assume this affects all Platforms, but I was using PC (UEFN), Switch 2 (Game Client) ### Video [![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/8/4/48477e27712b354552f6a41f8a0a0e97d33dec80.jpeg "UEFN Pop-Up Dialog Device Indexing Bug Showcase") ](https://www.youtube.com/watch?v=6XT-o7sJZO4) ### Additional Notes This bug is probably best left **unpatched** , but rather acknowledged instead to avoid breaking existing islands. ---

I feel this needs fixing as how would you know this going forward. Its needs changing so the buttons are in order. ---

This has been reported a few times, it’s in the “to be fixed” list from my understanding. It’s been like this for a long time. ---

The buttons need putting in order its as simple as that then it wouldn’t be an issue. If this was done when i posted above it would have saved numerous posts, time ect ect ---

They only fixed it on the device if it’s set to timeout.. still the old order on the non-expiring version.. ---

The device has a checkbox for if it should expire and close after a certain amount of time. That checkbox changes how the buttons are labeled. With it turned on they are 0,1,2,3,4,5,6,7,8,9,10,11 and with it turned off they are 0,1,2,3,4,5,7,8,9,10,11,12 ---

What a find.. I’d highly recommend just never using this device anymore. It may seem a bit of work but using UMG with verse is far superior now as the popup device is riddled with bugs still unfortunately. ---
