[Seaside] Alternative to call:

[Johan Brichau]

Hi Jeff,

Mind that #call: is documented in Seaside to “replace the receiving component with the argument component”. So, the receiver of #call: is equally important as its argument. 

Sending #call: to the session presenter is something you can do indeed. It’s not a ‘wrong’ way to do it (imho), but I think it's cleaner to parameterize your component with the component it should replace when using #call:.
Components are intended to be reusable and if some of the callbacks they render are intended to replace another component (e.g. toplevel), then it’s a dependency of the component. So, I would add an instance variable to your component that you assign when you instantiate the component. In your use case, you would pass the toplevel component when instantiating. Immediately, you have made your component more reusable as well, which is the core concept in Seaside ;)

cheers
Johan
