MSSQL throws "Violation of UNIQUE KEY constraint" Exception when using Subprocesses ----------------------------------------------------------------------------------- Key: JBPM-2702 URL: https://jira.jboss.org/browse/JBPM-2702 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.1 Reporter: Flavio Donzé Assignee: Huisheng Xu Fix For: jBPM 4.4 Attachments: jbpm.hibernate.cfg.xml We were using Postgresql and did now some tests using MSSQL. All processes containing subprocesses throw the following exception: java.sql.SQLException: Violation of UNIQUE KEY constraint 'UQ__JBPM4_EX__C4971C0E06B7F65E'.

DefaultIdGenerator.createId() when calling session.save() of the ExecutionImpl. At that point ExecutionImpl does not have an ID. We use JTA Transaction types see attachment maybe this is the cause of the issue?
