Missing Group Name

I create a test action which executes some tests - I don't give it a group name.

I run the build

On the Execution Details page I click the Tests link by the log link and get:

Server Error in '/' Application.

The parameter "GroupName" is missing.
Parameter name: GroupName
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Inedo.Web.HttpArgs.HttpArgumentMissingException: The parameter "GroupName" is missing.
Parameter name: GroupName

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Stack Trace:

That field is supposed to be required. We will update the behavior of the control to display an error message if no group name is supplied.
