[jira] Commented: (ODE-511) Hibernate DAO + OnEvent + Correlation error

["Sean Ahn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ODE-511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671385#action_12671385 ] 

Sean Ahn commented on ODE-511:
------------------------------

Rafal,

Are you using the same correlation id for the two requests?

A partner link, an operation and a correlation id determines a process instance uniquely. So, you cannot have multiple process instances with the same correlation id within the same process. 

To a certain degree, ODE supports multiple instances with the same correlation id. But, inherently, there's limit on how far it can go. Furthermore, there's no guarantee that all requests will be idempotent when a process becomes a complex chain of web service calls.

By using the 'unique' attribute, you can make sure that you always get an error on the client when you have multiple process instances with the same correlation id.

Let me know if your problem is different from what I explained about and if you have more questions.

Thanks
