Validation - Revert Record question

[deego55]

Hi. I have a layout that has a portal for comments. I set a validation on the comments so that only records that were created by the logged in user can be edited or deleted [Get (AccountName) = REC_CREATE_ID] where REC_CREATE_ID is Auto-enter account name.

This works but there is a problem. If the user edits any of the information on the main layout then tries to edit a record in a portal that they did not create, they are presented with an error message and option to Revert Record. If they revert, all the changes to the main layout are reverted as well.

Is there a way so that ONLY the changes in the portal are reverted, and the changes to the main layout are not affected?

Thanks so much!
