I wanted to use UMG ViewModel in my widget communication system. It works with no issue on default widget creation. But I’m also using Common UI plugin which uses the stacked widgets, activate/deactivate widgets etc… and it seems it didn’t work this plugin.
I tried several times to get it to work in my own project but it didn’t work.
Solution:
Finally, I completely removed the plugin from the project, deleted all the ViewModel-related assets I created, and enabled the plugin again & built it from scratch. It worked this time. It’s really weird.
