R2020b: Custom Simulink Library appears empty in Simulink Library Browser

Hello.

We work collaboratively on a Simulink Project and have a custom Library. We started work with R2019a and have since upgraded to R2020b.

We have top level library that contains subsystems linking to sub-libraries. In R2019a creating a new empty library, saving it with contents and a unique name (e.g. "LIB_somethingOrAnother") worked well. Next we create a subsystem in the top level library and set open callback to open sub library.

Custom Libraries created in R2020b appear to be empty when opened in the Simulink Library Browser. When you open them in Simulink, the blocks are there.

I just want to understand if we do something wrong or if this is a bug.

Thank you.

hello, I have the exact same behaviour.

Hi,

I solved it by setting the EnableLBRepository option of the sublibraries, check here https://fr.mathworks.com/help/simulink/ug/adding-libraries-to-the-library-browser.html

What's strange is that I don't remember having set this option in R2019b for the sublibrary that was displayed in the browser.

You are the best!

Thank you

I am certain I have never done this before...
