Finder method giving : ERROR org.hibernate.event.def.AbstractFlushingEventListener - Could not synchronize database state with session -------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-2247 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2247 Project: Hibernate3 Type: Bug Environment: Hibernate 3.2, Oracle Reporter: Gibu George The scenario is like I have a page where I can create a new entity, the first time when I create the entity it works fine with a particular code which is a Unique key on the table, then I tried to create a new entity with a different code that also worked fine. But when I tried to change the code of second entity to the same as that of the first one, in my *validate method* which tries to *find* whether there any enitity with such a code, it gives the follwoing stack trace. This is happening before the save is called also if I try to refresh the page after the error occurs it works fine and gives a proper validation failed message.
