MDM Data Manager Crashes

Hi All,

I am using a slightly modified BP-Repository. After a couple of changes to the data model my data manager keeps crashing when trying to save a record in the main table. The log says:

Assertion failed. index != ID_NOT_ASSIGNED

File name: ..\..\..\MDM\RichClients\DataManager\ExpressionsPane.cppLine number: 142

Looks like I deleted some fields for which a validation was assigned. When I try to access the validations tab in record mode the dm crashes immediately. How can I fix this problem or delete all validations?

Thanks,

Ingo
