Great job
But just after I wanted to add environments.
In http://localhost/Octopus/Environments clicked Add environment
Entered
Name: DEV
Description: Development environment
After click in Create I’ve got validation message: The Name field is required.
I can confirm the same issue. I can also confirm that it works by adding a ?name=foo GET-parameter to the action url (/Octopus/Environments/Add?Name=foo).
However, i can not se any reason to why it’s not working with POST. It’s verified by Firebug that a “Name” parameter is being sent.
A new build is available from here that fixes the issue:
Fixed
Yep, fixed. Thanks!
