Hi All

With FB 1.52 RC3 I tried to place a Foreign Key

ALTER TABLE APK ADD CONSTRAINT F_APK_GROUPID
FOREIGN KEY (GROUPID) REFERENCES APKGROUP
(APKGROUPID)

But at commit it gives

ISC ERROR CODE:335544351
ISC ERROR MESSAGE:
unsuccessful metadata update
object APKGROUP is in use

This happens even after shutdown, gbak backup and restore, reboot

Does anyone know a solution ?

regards
Tanno
