Crash on change/undo UMG widget values

Development Programming & Scripting UI
, , , , ,

To Reproduce:

1 - Create a new Project and create a Widget Blueprint.

2 - Open the Widget Blueprint and drag a Image widget to the canvas.

3 - By default the image have a Size X of 100, click to edit it, manually select the number “1” and type “2”, press Enter to confirm and then press CTRL+Z to undo, the engine shall crash.

More Info:

If I click to edit the value and just type a new value replacing the old number completely, it won’t crash.

But if I manually replace only one number as the example above or add a number, for instance setting it to 1000, it crash when doing a undo.

Happens with any widget.

Tested on 4.14, no crash there.
