Undeletable Dispatcher Events

I have somehow managed to produce undeletable Dispatch Events.
I had Event Dispatchers Event_StepLeftFoot, Event_StepRightFoot and Event_JumpApex declared in my animation blueprint. Than I decided to move them to parent C++ class, and declared event dispatchers with the same name there.

After reloading code blueprint’s dispatchers became renamed to Event_StepLeftFoot_0, Event_StepRightFoot_0 and Event_JumpApex_0, and they became undeletable, unreanamable and this warnings start to appear. I renamed my dispatchers in C++ class, but it helped nothing.

Hi ,

Does this occur in a clean, blank project with no additional content or is it limited to one project? What steps can I take to reproduce this error on my end?

Hi ,

We have not heard from you in several days. I am marking this as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information.

I got a crash trying to recreate the problem.

And after that I have project with bugged dispatchers.

Hi ,

What steps can I take to reproduce the error you are seeing with the project you linked?

Where are you seeing the errors occur?

Hi, .

If you open any anim blueprint you should see compile time warnings which I described in post.

To reproduce, you can start with empty project

  1. Add c++ class derived from AnimInstance
  2. Create two animation blueprints derived from created c++ class
  3. Add Event Dispatchers with some names to AnimBlueprints, build and save project.
  4. Open c++ class and add event dispatchers with the same names to it.
  5. After recompile it should crash,
  6. After reload it will report warnings in blueprints.

Hello ,

Can you give an example of how your Event Dispatchers are being set up in code? Are you doing anything with the Event Dispatchers in blueprint other than just creating and naming them? Are you assigning/binding them in any way?

No, I am not doing anything with them. Sean, can you open eventdispatcherbug.rar (3.5 MB) I attached to previous reply? It have all source code in it.

This is a bug that has already been reported, UE-21368, and is currently in the pipeline to be worked on. Thank you for your information and repro steps.
