Calling a stored procedure in mysql from .NET throws error - all parameters must have their type explicitly set.

Question

I have a page which submits a form in my local system but in my production system when i click my submit button it just freezes with the error in my web developer toolbar saying

Error: Sys.WebForms.PageRequestManagerServerErrorException: When calling stored 
procedures and 'Use Procedure Bodies' is false, all parameters must have their
type explicitly set.

EDIT:

I am using mysql.data.dll version 5.0.7.0
