Dynamic member in a FlexForm error

Summary:

I have a FlexForm that have a mix of stored and dynamic member. The expectation is that when submitted, it'll submit data from the stored members, but will ignore data in the dynamic member. That's exactly what it does, but while doing that, it gives me an error:

The actual error description is, "A method called by the script failed on line: <line number>, with error: Batch calc error, FIX statement cannot contain Dynamic Calc member from dimension [<dimension name>]."

The error message only has one button; it doesn't ask me whether I want to continue running the script (that would warrant some user reaction). So, for me it's just an obstacle that prevents a full automation of running multiple unattended uploads via the FlexForms.
