Hi @knstvk and @firstova,
The user on China forum encountered the same issue here in CUBA 7.2, related toptic is : https://forum.cuba-platform.cn/t/topic/1022
Also uploaded the 2 projects here: cuba.rar (2.0 MB)
Reproduce steps:
- unarchive the attached file, it includes 2 projects: embeddandembeddtest(pls ignore word spelling here ) )
- open embedd project with CUBA Studio 13, then run CUBA->Advanced->Install App Component, it should be successful installed.
- open embeddtest project, then run CUBA->Generate Database Scripts..., verify that scripts for both the App Component and the main project are created.
- run CUBA->Create Databasein project embeddtest
- start embeddtest by click the runbutton of Studio.
 Will observe a dialogue listing update scripts:
 
 The content of these scripts is removing embedded entity columns from the table created in the App component.
 
Could you please check if itβs a bug or work as designed? if the latter, please explain this behavior.
Thanks!
