I am working on a couple of custom workflows for the latest Umbraco Forms version and I am trying to set default values for my custom settings. I'm assuming that I should be able to do this via the prevalues option on the Settings attribute but it doesn't seem to be working for me.

Example:

[Setting("Subject", description = "Enter a subject for the email", view = "TextField", prevalues = "Thank you for your enquiry")]

In most cases I simply want to prepopulate the text boxes with default text.

Am I missing a trick somewhere?

Cheers, Simon
