Removing stylesheets in symfony 1

Today I encountered a situation I've not encountered before: I have a project-wide stylesheet that should be used for everything, except one specific module that has different (brandable) stylesheets. I created a view.yml for this module with a different stylesheet, but of course the configuration files are merged so it doesn't actually overwrite the main stylesheet file. And this wasn't really what I needed here.

So I started searching around, and quickly found the removeStylesheet() method in the sfWebResponse class. This didn't work however, when I called this in my controller. Googling around a bit more I found this mailinglist discussion where Alexander Deruwe describes exactly what I need to do! Instead of removing it programmatically in the controller, I can just do it in my module view.yml file. So my view.yml of the module now looks like this:

stylesheets:    [-main, formdefault.css]

By negating a stylesheet that was added on a higher level of configuration, it is removed again from the set of stylesheets, and not added to the actual response. Thanks Alexander!
