Components not visible in view in flow ui

Components not visible in views in flow ui with latest build. Restart will show front end development build … but nothing happens.

What should I do?

Hi,

Which version of the Jmix Studio plugin are you using?
And could you attach logs from the console (click ‘Console’ button in designer)?

Regards,
Mikhail

You have node version 16.14.2 on your computer, try updating it manually as workaround if this error occurs constantly and it cannot be avoided.

We already have a ticket with a similar problem: IllegalStateException: Failed to install Node · Issue #2177 · jmix-framework/jmix · GitHub

Also since Jmix Studio version 2.1 we have separated the Preview and Jmix UI tool window. This change will help to avoid problems working with descriptors (Component Hierarchy and Component Inspector) due to similar problems with previews.
