I have a error using a master-detail with UniQuery/DatasetProvider/ClientDataset. When there is a exception in detail, my program don´t cancel the transaction and the master is saved. It´s necessary any configuration in DatasetProvider?

Please provide the following information:
Which provider are you using?
Whether an exception occurs when you you call the ApplyUpdates method for the detail TClientDataSet?
When do you call ApplyUpdates for the master dataset?
Do you start a transaction manually?

-The provider is InterbaseUniProvider.
-I don't call ApplyUpdates for detail ClientDataset. In Master-detail mode is enough to call ApplyUpdates to Master ClientDataset.
-I call ApplyUpdates for the master dataset after call Post Method.
-I don't start a transaction manually. The DatasetProvider controls the transaction.
