Operation is not valid due to the current state of the object (client : ODAC 11.2.0.1.2 with Oracle

  Hello,

I'm working with the ODAC 11.2.0.1.2 Client and with an Oracle Server : 11.2.0.1.0 (x64)  (Entreprise)

I'm working on a stored procedure and deploy it in the server.

When I try to open a connection, it seems to work because I've got the connection state set to 1 but, when I want to execute a query or a procedure, i've got an exception :

message :Operation is not valid due to the current state of the object.
