synchronization error

[btvandijk]

I have a setup of GSCF and SAM. Notification is set to true. I try to import a study. I first fully import it into GSCF (including assays). After this I want to add data to this study in SAM. Since this is a new study, the synchronization tries to get the new assays, but it fails (with the message: An error occurred while synchronizing: object references an unsaved transient instance - save the transient instance before flushing: org.dbxp.moduleBase.Assay; nested exception is org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: org.dbxp.moduleBase.Assay). Even as an admin I receive this message. I have included screenshots of my SAM-terminal with the call (a) and part of the stacktrace (b).

We found a workarround by:

1. creating a study without assays
2. logging in as admin to SAM and force the synchronization (by browsing Assay's)
3. editing the study in GSCF by adding the assays
4. forcing another synchronization in SAM

We have concluded that this error is probably caused by a dirty database. Somehow a study was duplicated in the database, and clones of all the assays and samples were made. The measurements were linked to one of the studies, but updates from GSCF (changes in assay names) were applied to the other.

Deleting the copy that GSCF made changes to resolved this problem. Next synchronization GSCF updated the one remaining instance of the study
