Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Hi Genova,

Thanks for the report! I was able to reproduce this in 4.9.0. It looks like we have a new Note system, but I don't see any reason for this particular instance. I've created a bug report for the issue (UE-20613), and I'll let you know when I see an update on it.

In the meantime, the Note shouldn't interfere with the functionality of an array input. Please let us know if you see any additional problems with this. Thanks again!

Hi Ben, any update on this?

It's marked as Fixed for 4.11, though I'm not sure yet whether it's in the Preview build. I'll be verifying the fix this afternoon, and I'll let you know =)

Just verified this is fixed in our internal Release branch. It did not make it into the 4.11 Preview 1, but I would anticipate it being fixed in the following Preview build.

In any case, it hasn't caused any issues as far as I can tell. It's just a note

Hello,

I've just attempted to reproduce this issue in 4.11.2, and did not experience the Note appearing on the Custom Event node.

Here were the steps I followed:

  • Create a new blueprint

  • Add a custom event

  • Add an input of any type

  • Make the input an array

  • Compile the blueprint

Doing this, no note appeared on the node. What steps are you following when you are seeing the note appear?

Well, I have the same issue (blue note, etc.), although it does not show on custom events inside a graph, but it appears on an interface event. I have my main character calling an interface function, this function's input is an array made of a specific Actor bp. Then I use this function as an event into my GUI (umg) and the note appears on that event.

See image :

EDIT :: I forgot to mention that moments ago it was working fine, but when I did another manipulation (not connected to this thing) the note appeared after I compiled again ...

As this post is quite old, would you mind creating a new post for this in the Bug Reports section of Answerhub. Please provide a detailed list of steps we can follow to reproduce this in a clean project.

I just want to add for anyone else that stumbled upon this issue, that by saving all and restarting the editor, I was able to remove the note. Interestingly, I had an old custom event that I added an array input to, and it worked fine. I then made a new custom event, added an array, and that's when that note appeared. That's what led me to believe that restarting the editor would help, because I know from other issues that restarting can help all your blueprints recompile and have clean communication, and the new custom event may not be communicating with everything cleanly yet.
