Error changing metatdata of a document straight after upload

[amarg]

Hello Experts,

I would like to hear from people who have come accross the javascript error below and also understand how you resolved it (if anyone managed to):

Wrapped org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException: Object of class [org.alfresco.repo.domain.hibernate.NodeImpl] with identifier [18869]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.alfresco.repo.domain.hibernate.NodeImpl#18869]
‍‍‍

My actions are:

1. I create a custom button in the document toolbar that calls a custom action for a single file upload which then calls a webscript when successful.
2. I try to change metadata and save the recently uploaded document within the webscript and this is where I encounter this error. I have confirmend that the error is not related to the changes I make to the document.

I suspect this has something to do with transaction management in Alfresco. Any information would be highly appreciated.

Not sure, buy have you tried to save the document before change the metadata, then change it, and then save it again? Some time ago I have a similar problem, and that was the key

I have tried that palba and this had not worked. Regardless of whether I change anything, I get an error when I call doc.save().

The interesting thing about this issue is that, although I do get an error message, all the changes happen as expected i.e. the metadata gets updated after the script.
