I'm testing Unidac against Firebird in a multitier application:
Unidac + datasetprovider (application server) + ClientDataset (client Application) .

With all tables i'm receiving in clientdataset (OnReconcileError event):
"Record not found or changer by another user" when i try to insert or update record.

Provider flags are correct and i'm using DatasetProvider.UpdateMode = upWhereKeyOnly .

I have no problems with AdoQuery (dbGo) or FibPlus in same tests.


Do you have any idea?

thanks in advance.

It's working only with DataseProvider.ResolveToDataset = True and using separated (dedicated) Transaction and UpdateTransaction in Uniquery.

If i try to use common Transaction and UpdateTransaction with all Uniquery components in Datamodule i see server active transactions number increasing after any update, insert or delete operation (it's bad for firebird).

I think you have some issues with IProvider support in UniDac. I want to order Unidac but Iprovider working ok is very important to me.

Can you help me?

We have fixed this bug. This fix will be included in the next build of UniDAC.

Do you have a date for this release?
