I just tried it with a private window in chrome (53.0.2785.143 Built on
Ubuntu) as well as firefox (49.0.2).
The following seems to work in current master (2.4.0.CR-1 c3f3c5c)
Steps:
1) User Federation -> add provider -> example-user-storage-jpa
2) click save (note the cache policy stays empty NOT default -> which
changes to DEFAULT after save)
-> Success message -> now I can edit the storage provider without problems.
The following does not work
Steps:
1) User Federation -> add provider -> example-user-storage-jpa
2) select CachePolicy: Default
3) click save
-> Error message...
Same in firefox and chrome.
With the latest keycloak release 2.3.0.Final I can also reproduce the
problem in chrome and firefox
Steps:
1) User Federation -> add provider -> example-user-storage-jpa
2) click save
-> Success message
Priority is empty after save...
3) changing priority to 10
4) save
-> Error message
