UE4.7 Cannot recreate a widget anim with the same name after delete

If you create a widget animation, delete it, and then later try to recreate it, it gives a duplicate name error.

Steps to repro:

Create a new widget blueprint.

Add an empty animation, called “New Anim”

Select this animation and delete it.

Add a new animation and try to give it the same name, “New Anim” it will give you an error saying the animation already exists.

Even if you save and compile you will still get this error. It requires a full shutdown of UE and a restart before you can reuse the old name.

No prob! Just doing my part and reporting the bugs as I find them.

Hi Furroy,

This is a known issue with asset names. UE4 keeps a cache of names that have been used in that session which does not clear until the engine had been restarted. This will also occur with any .uasset file or custom event node for instance. Our developers are aware of the problems this may cause and are working on a solution.

Thanks!
