Yes, I did that !

I'm Sure !

I did that too, And I'm sure that it is correct.


I was wondering if the problem could be related with inheritance of
datamodules like that :

TIbDataModuleConnection ---->>> TThisAppDataModule

TIbDataModuleConnection has One TIb_Connection, but it just make
part of the application, it never is instanciate, just
TThisAppDatamodule does.

It is important to note ( and i forgot to say ) that at runtime,
IT NOT raises any erros, and works fine , just at develop time (
Database name could not be blank , or something like that )

yep, the dataset is linked to the connection, but the connection
appears to be not correctly configured, so this problem could be
related to the one below.
