What does the error say?

#

I'm checking it now

#

No error log. It just says "ERROR" 😄

late raptor Apr 11, 2024, 5:59 PM

#

Without pressing compile, go to "Window" at the top and check for "Compiler Results"

#

Not sure it's actually there, but that is the window that is usually at the bottom

#

That should have an error in it

Checking

#

I have checked output log, and it says something about delegate

#

(SENDED NEW ONE)

#

Hm, is this a C++ function or a BP one?

#

It seems like the node can't figure out the delegate type properly

#

Sorry, i didnt send half of log

#

All errors about delegate

#

Maybe an engine bug?

#

Could it, where is that node coming from?

frigid flare Apr 11, 2024, 6:07 PM

#

My function library

late raptor Apr 11, 2024, 6:07 PM

#

The way it reads is that it tries to "create" the node, then can't find the Delegate inside the WB_ItemMenu, which probably doesn't even have a delegate with that definition.
And then it checks against the connected event and fails. Compiling it might work cause it's a load-order issue, but not sure.

frigid flare My function library

But how is the actual Signature of that Delegate defined?

#

A Delegate usually has a Signature, something it expects as Inputs of the connected events.

frigid flare Apr 11, 2024, 6:08 PM

#

it appears every time i open project, until i compile

#

late raptor Apr 11, 2024, 6:09 PM

#

Yeah, again, might be a load-order issue. Not sure. I've seen this on a customers project once.

frigid flare Apr 11, 2024, 6:09 PM

#

Could there any solution for me?

late raptor Apr 11, 2024, 6:09 PM

#

Right, so WB ActionScreenWidget has the Delegate

#

What happens if you cut the Function Library out of the equation

#

So directly use the CreateWidget + Bind in the ItemMenu?

#

Just for testing fwiw

frigid flare Apr 11, 2024, 6:10 PM

#

I know that it'll work. It was like that few hours ago :) I just added it to the function library and tried to get rid of some overcrowding, but it obviously causes some problems

#

I think the best approach is to use Create and Bind instead of my function. Thank you for the help
