context_name is unpermitted when trying to create list from web UI

[ssoulless]

Hello, Im using Rails 4.2.0 with ruby 2.1.4p265

Im trying to integrate maily_herald and maily_herald_webui to an existing applciation, well the process is going good, it shows the web interface. I began fixing and adding some things you can check them in my pull request #1

Well I began testing the features like create a list through the web UI, well it creates the list the the context_name is always 'nil' so it breaks the app.

I checked the code trying to fix it, but I do not know how to proceed in this case the permitted params for the lists are in

https://github.com/Sology/maily_herald-webui/blob/master/app/controllers/maily_herald/webui/resources_controller.rb#L136-142

well I do not know how that reource_spec.params is working could not find why it is not permitting the context_name param...

any idea?
