I have created a new entity extending the User entity, and check the replace parent option.
When i try to create standard screen via studio, it fail with error message :
java.nio.file.AccessDeniedException: C:\Users\xxx.haulmont\studio\cache\com.haulmont.cuba\6.2.5\cuba-desktop
But if i downgrade Cuba version to 6.2.1 it works. Please solve this issue.
Thanks.
The ~.haulmont\studio\cache folder contains the downloaded sources of the platform by version. It seems that something on your system prevents Studio from accessing files of the 6.2.5 version.
Try to remove the whole ~.haulmont\studio\cache\com.haulmont.cuba\6.2.5 folder (it will be re-downloaded) or simply reboot your machine.
