UMG Combobox clones Options

I’m attaching and detaching the Widget dynamically to the Viewport. Every time it’s attached it clones the available Options of each Combobox.

Repro:

  • Create a Widget containing a Combobox with some Options
  • Add Widget to Viewport
  • Check the available Combobox Options
  • Remove Widget from Parent
  • Add Widget to Viewport
  • Check the available Combobox Options (any Combobox Option should appear twice)

Quick questions:

  1. What version of the engine are you using?
  2. Can you reproduce this issue in a clean project?
  3. If so, are there any small steps that may have been left out of the original post?
  4. Could you provide screen shots of the blueprints involved with this issue?

Yes I can and I uploaded you the clean project for further investigation

Hello AlexW88,

I was able to reproduce this issue on our end. However, after doing a bit more testing I found that this issue has been resolved on our latest internal build. The fix will be available in an up coming release of the engine. Thank you for your time and information.

Make it a great day
