Using latest version of ODAC (5.55.1.22) and Delphi for development.

2 Tables are linked over Master-Detail-Relationship. The Relationship is set with MasterFields, Detailfields and MasterSource.
Everytime i change a Field (any Field) in the master-dataset the detail-dataset is refreshed. If i change 5 fields 5 times a refresh is called.

This means also for each field which is filled in the event OnNewRecord of the master-dataset a refresh of the Detail is done.

This reduces the performance enormous, especially you have many records in the detail-dataset.

I think it's only necessary to refresh the detail-dataset if the masterfield is changed. Can you fix this:?:

TIA

We couldn't reproduce the problem.
Please send us complete sample to demonstrate it and include script to create server objects.

I've just sent the mail with sample code to Dmitry.

Thank you for your sample. It does help us very much.
We reproduced your problem and fixed it. This fix will be included in the next ODAC build.
