Hi all, So I tried to crete a new realm and use a theme used also in a different realm, but all I get is the errormessage "Error! Realm with same name exists" when trying to apply the theme (click on save). Logs are stating this: 2018-03-06 10:50:32,065 INFO [org.hibernate.engine.jdbc.batch.internal.AbstractBatchImpl] (default task-25) HHH000010: On release of batch it still contained JDBC statements 2018-03-06 10:51:38,652 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-50) SQL Error: 1400, SQLState: 23000 2018-03-06 10:51:38,653 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-50) ORA-01400: Insert NULL in ("MY_TEST"."REALM_SUPPORTED_LOCALES"."VALUE") not possible* Steps: - I created one realm called "MYREALM" and applied the logintheme there without a problem (used kc standard for admin and so on). - Then I created the other one "MYREALM_DEV" and tried to apply the custom theme. - To check if its depending on the theme, I tried to apply the base keycloak theme, same effect. This workflow worked for another application perfectly with one theme for different realms. seems very weird, as if the realm is created on db-level with same name as the old one instead of my given name. So, Could anybody give me a hint why SQL fails here? Or point me to the relating DB Tables please so I could investigate further myself? Thanks in advance!
