NI Library Icon problems in classes

[Bakur]

LV2021 is the last one supporting PharLap OS. Anyone knows if there are any perspectives on getting a bugfix for LV21?

I haven't heard of any plans to patch this bug in 2021 SP1, but I have made LabVIEW R&D aware of this thread and your request.

Have been using the "Apply to all VIs" after editing a class icon quite a few times now in 23Q1 and have not run into this issue. So far 😁

Just as a quick hint for everybody keeping using LV2021. If you want to prevent the problem with VI Icon overriding with blank, rename a layer to a different name.
It seems as if renaming the layer name "VI Icon" to "VI Icon1" does the trick.

This unfortunately has to be done for each and every icon in the lib, but it can at least prevent some frustration when you have well designed icons and not only some text inside...

In my understanding this override happens to all VI Icons that only contain default layer names like "NI_Library" or "VI Icon". As soon as you drop a new layer (e.g. a glyph) this problem seems to disappear.

My technique to avoid icons resetting with LV2021 was to drop an instance of all the library members (VIs/controls) on a single diagram (like a VI "Tree"), which I kept open during the library icon modification. By doing this I never had my icons reset again.

Ha! That really seems to work! Thanks a lot, that is way faster than editing the layer names of each VI 😁
