ADF  Struts Row currency error.

We are receiving the following error intermittently in multiple areas of our application:

Row currency has changed since the user interface was rendered. The expected row key was null

It can be duplicated on multiple screens such as: Multiple screens for creating new records in a popup (always occurs on save), Deleting on a Master Detail screen (occurs on delete and confirm delete).

The error is intermittent in that you can create or delete multiple records without error and then all of a sudden it errors.

I have tried the suggested fixes, but they either did not work, or were ADFaces related.

All <action> definitions use className=oracle.adf.controller.struts.actions.DataActionMapping and type=oracle.adf.controller.struts.actions.DataForwardAction (or an extension of DataActionForward) and use a set-property similar to <set-property property="modelReference" value="WEB_INF_createOpUIModel"/> to bind to the Model&.

The error is hard to reproduce within JDeveloper 10.1.2, it takes multiple creates executions (up to 40+) to get the error to occur, however as a requirement we were tasked to deploy the entire application to a laptop (DB, APP server, etc).  On the Laptop it is very easy to duplicate, within a couple of create executions (could this mean it is resource/cache management related???)

Any help would be appreciated before we are forced to rewrite these processes circumventing the ADF model and using something else&.

Thanks in advance.

Update: We found an error in the app logs which was a ps_txn pk constraint violation. After truncating the ps_txn table we are unable to duplicate the currency error. We will continue testing to ensure this is an actual solution.

Any information on why this worked and how to prevent the error in the future would be awarded points. Thank you.

This solution is bogus.  I was duped into joining this web site to get an immediate and respectable answer to my question.  Not they have my email mail address.
