Hi, I have two Taureliusdataset components joined in master detail relationship and attached to them there are datasource component and TTMSFNCDataGridDatabaseAdapter at last.
The application works fine until I edit the field of the detail dataset. As soon as I confirm the value an exception is raised ( attached screenshot).
Unfortunately not, for now.
I'm afraid we need a sample project reproducing the issue, as there might be many reasons for that and we have to know what you are doing.
