LabVIEW 2023 Q1 - New VI for Override does not adopt the icon of the parent method VI


I have recently started using LV2023 Q1. I write my programmers purely with the Actor Framework, and in this regard, I have noticed that LabVIEW no longer takes the icon from the parent methods of the VIs for Overrides from the Actor Framework. Even self-written methods that I overwrite in the child class no longer adopt the icon.
Is this a bug or a new feature?
Is there any way to change this?
Generating a new icon for an overridden VI every time is very time-consuming, especially if you only work with actors like I do and often overwrite the same VIs.

must be a bug... this page just created a month ago mentions the automatic icon creation and no mention of being able to turn it on or off.

Not sure if a bug report was filed or not, so I have created one as well just in case. Report number 02144269.

I contacted NI and only got a response from them last week:

we have created bug case 2350519 to resolve this issue. I have received confirmation from RnD that there is currently no suitable workaround for the version that presents this problem.

In this regard, please expect a workaround for this issue in the upcoming release of LabVIEW or the upcoming patch for the reported version.

Barring catastrophe, this bug should be fixed in LabVIEW 2023 Q3.

I don't have a workaround for the bug, but I do have a procedure that's been helping me fix the override VI icons quickly when the bug occurs. This procedure assumes you use mostly text-based icons on your method VIs. Let's say this is the parent icon:



Due to the bug, when I create a new override of this method in a child class, I get this:



Now here's where Quick Drop comes in. Press Ctrl-Space, type 'from action str' in Quick Drop, then press Ctrl-K:


The Ctrl-K Quick Drop shortcut will assign a text-based icon to the VI based on what you typed:



This feature was first introduced in LabVIEW 2020, and I use it all the time, but I've been using it even more all the time in LabVIEW 2023 Q1.

if it is not a text icon, another trick is to drop the one with the correct icon on a block diagram, highlight the VI then Ctl+C, then open the icon editor for the one that is missing its icon and ctl+V. 

In general that works. Not sure how it plays with class banners, so YMMV.

I have a feeling you can drop an icon from one vi onto the icon of another vi and it imports it, so there might be a quick way there to recover the missing icon info. Maybe worth a look (I'm not able to test this right now).
