When i say "the destination view (where command should execute) should be
passed as a parameter.", i didn't mean that command gets executed in the
view. ;)
I meant that i need to know the component name because the command is gonna
change things in this component (and thus pass it as a param in my dispatch
event). That's why initially it was a view function.
As to "if the function performs some buisness level task, it should be a
command" i'm not sure of this.
In theory, yes.
But in some cases, you will have to update a view by adding or removing
children, or even doing much complex things which are not business
dependant. Things which will require actionscript, and thus a function. And
i don't see how using bindings could resolve all these issues.
Unless you tell me there is a way to trigger a local function by listenning
to data in ModelLocator.
Sorry if this sounds confusing, but as you might have guessed, english is
not my original language.

Commands don't execute in views. They execute in their own space, and update
things in modelLocator if needed - all you views are binding to modelLocator
for their data, no ?
As to " when does a function in a viewHelper or viewLocator (or MXML file)
merit becoming a command?" I'd say, if the function performs some buisness
level task, it should be a command. Otherwise not.
