multipart/fom-data complex field names

[Jonlee2001]

Hi,

I'm trying to call an API (mailgun) which requires the use of "complex" field names when sending post requests - i.e. "v:my-custom-data". There seems to be no way to specify "complex" field names without groovy/grails interpreting them as constant expression rather than a variable expression.

Is there a way to do this? or is it not supported?

Jon
