Description

There is a mistake in the book, here: http://www.symfony-project.org/book/1_0/07-Inside-the-View-Layer#Component%20Slots

To disable a component slot for a given module, one is invited (in listing 7-43) to do this in the module's view.yml:

all:
  components:
    sidebar:  []

It doesn't work. The following does, though:

all:
  components:
    sidebar:

Curiously, this also works:

myActionSuccess:
  components:
    sidebar:  []
