Thanks,

But it still gives me this error.
What gives me a very bad feeling is that even dough I get connection
to my database and the database connection is active, I still can't
get the list of my stored procedures at the TIBOStoredProcedure
component. However, if I fill in the name of the sp by hand, it finds
the sp and puts the right parameters inside the params property
