Second call of stored procedure throws ORA exception

Question

I am calling a stored procedure in an Oracle database via Nhibernate in my app. The first time I call it everything works fine and I get a result but the second time I get an ORA-00942 (table or view does not exist) exception. Any idea what could be possibly wrong? The procedure just return me an object. No changes are done. Thank you for your ideas.

So I have found out the mistake. It was a bad WCF config. It was missing section because some guy deleted it. Thank you for your help.
