LED font color change works only for the first time #2639

I realy like the feature that the LED font changes the color base on the backgroud color, if the color is dark, the font changes to a white color, it is good for the readibility.

But it only works once when the OPI is initialized by running it or reload it.

Please look at the video.

Since this is for the display builder and phoebus, you could have posted this issue there, not in the Eclipse/BOY based repo. But anyway, the display builder examples for "LED" contain a more reproducible setup since it's using local PVs, so anybody can execute that display. When I try it, the color changes as expected:

Same with the "Byte Monitor" example:

What do you get for those examples?

Thank you very much for your answer and please forgive me to post this issue in the wrong repo.

I've had a look at the examples, and now I found the probable reason, maybe it is because my Enum PV doesn't have the right definition on the fields, which means that the bi record just have a "ONAM" filed and there's no "ZNAM" field.

I will fix the field definition and test this again.

Thank you again.

I have created a new issue in the Phoebus repo.
