Ebean.saveManyToManyAssociations

[pov...@hotelston.com]

Hello,

we recently changed ebeanorm version from 3.2.5 to 4.1.6. We have discovered that Ebean.saveManyToManyAssociations method is no longer working. We receive following error:

org.postgresql.util.PSQLException: Cannot commit when autoCommit is enabled.
    at org.postgresql.jdbc2.AbstractJdbc2Connection.commit(AbstractJdbc2Connection.java:703)
    at com.jolbox.bonecp.ConnectionHandle.commit(ConnectionHandle.java:564)

with version 3.2.5 it was working without any problems. Could you give us an explanation what might cause this error to occur or how to fix it?

Regards,

It seems that the jdbc connection pool being used is configured to be autoCommit = true ?  Is that the case?

In general Ebean is expecting the connections to be autoCommit = false in order to support transactions. There were changes in 4.x around how to deal with using autoCommit = true type jdbc transactions so perhaps that is the issue.  Can you confirm if you are using autoCommit = true ?

Cheers, Rob.
