I have a question about the correct use of a SQL Assembler destination. It seems that the SQL Assembler does not handle NULLs when data is passed to it from the flex client. If I have a value object with a NULL string attribute, SQL Assembler doesn't seem to recognize that the attribute exists. When performing an update a "Missing IN or OUT parameter at index:: xxx" error appears in the log.
If I change the code to make sure the string attribute in question has an empty string instead of a NULL before being passed to the server, the error goes away.
Is this by design? What is the proper way to handle this?
