Repeated Data Definition Group
I had a user report this, Bryce Roberts from Stone Ridge. Here is his report below:
When investigating an unusual issue with content, I found that there appears to be an underlying bug in Cascade related to repeated data definition groups. During moving/adding/delete of a repeated group ( like the accordion), the structure can become disassociated with the correct content, when an update operation (submit or draft) is occurring at the same time as change operation(move,add, or delete). I saw this occur with a draft update when a section was moved and the content of one section repeated (replacing another section). I also saw this on a submission and received the follow 500 error attached below. This is effecting both Standard Template sites and custom sites that use data definitions with repeatable groups.
I do not have a good test case since this appears to be something related to timing/post back interactions.
Sincerely,
Bryce

Hi Steve,
Based on Bryce's description, it sounds as though he is running into this known defect in which field values may become offset when adding/removing fields too quickly or when the auto-save draft is triggered while modifying fields.
We actually released a fix for this issue in Cascade Server 7.12, so upgrading should resolve the behavior.
Please let me know if you have any questions.
Thanks!
