Linked Reporter field in Forms input doesn't allow unknown Email address

[Martin Kirk]

When creating a Request Form (Forms) It's possible to override the standard input forms for a request input. 

eg: If i create a Text Input and Link it to "Reporter" from JIRA - the default Reporter input box on the Request creation page, disapears and instead it shows the one I created.

However !

The default Reporter input box, allows ALL email addresses. 

The custom Reporter input box, ONLY ALLOWS pre-existing users already added to the project. 

How do i fix this ? 

I want to use my own custom field AND allow all email addresses to be typed in.

The reporter field holds a "user", not free text.  It's not really a simple text field, it's a pointer to the account you select.

This means that you have to have an existing account to point to.

How does the standard email input work then ? 

The value goes to the same field in the JIRA ticket.
