UE 4.17 drag and drop not working

Development Programming & Scripting
1

I’ve created a drag and drop inventory from official Unreal tutorial with Wes Bunn, previously in 4.16 - everything works prefect, but soon as I update project to 4.17 drag and drop not working, when I press the button and drag nothing happen, no drag and drop widget is created, any ideas why? Please help

Cheers!

Tested on 4.17.0 source, you guys sure you did not mess up somewhere? Can anybody try it with that minimalistic setup?

EDIT: see Comment Bellow 100% Reproducable, confirmed Bug

We’re on 4.17.1 - didn’t change my Drag & Drop setup at all. Just upgraded from 4.16.2, was working fine there.

Also, you don’t use a button. It seems like using a button for drag & drop causes the issue.

Thats correct I used a Border. Tested it with the same setup Wes used in this Tutorial:

It looks like the “Click Method: Precise Click” does not do what the Tooltip describes.

At Epic: Steps to reproduce my Images above but instead of Border using a new Widget with Button as root of the Widget and the overridable On Mouse Button Down instead the Border Binding I used.

Looks like button always has higher Priority over the overridable Event of the Widget.

Reproducable 100% no workaround possible unless using a different Button than left Mouse.

Thanks so much for digging into this! Does anyone know how to best get Epic’s attention on this? This is a really big blocker for my project.
