The story:

There is a table with a trigger on it. The trigger calls a stored procedure. The stored procedure has no paramters, and the trigger does not pass any parameters to it.
STILL, when inserting in the table an error occures: "Procedure .... has no parameters and arguments were supplied."

Did anybody came across a similar problem?

PS: Probably it's just a simple minor thing that I am missing, but still, any ideas could help, even if they are the most common ones.
