Hi,

I have a simple stored procedure in SQL Server 2005 that's exposed
via an HTTP endpoint.  It has valid WSDL and can be called from
InfoPath without a problem.

It's a number fountain - pass it two string parameters and it
returns the next integer for that input.  We'll use it for naming
process instances.

I can add it to the process but if I try to use the method (see
images) then the process errors with the message: Invalid cast from
'System.String' to 'System.Data.SqlTypes.SqlString'.

Any pointers to getting around this message in Blackpoint/K2 Studio?

Thanks in advance
