[Springframework-developer] createBinder and initBinder added to MultiActionController

[Colin S. <col...@ex...>]

I've added createBinder() and initBinder() methods to 
MultiActionController, similar to what exists already in 
BaseCommandController. Right now there's no easy way to add custom 
property editors to a MultiActionController. Note that there's still no 
way to set a custom MessageCodeResolver strategy such as available in 
BaseCommandController, to apply to the binder. That arguably should be 
added as well.

Arguably, the whole MultiAction/MethodNameResolver concept needs to make 
its way into the BaseCommandController and subclasses in some fashion. 
When creating forms with multiple actions I've needed something similar, 
and handled dispatching by hand. I think what would perhaps work is to 
allow the properties to be set, but not to actually use them by default. 
That is, a subclass of BaseCommandController would have to manually 
invoke something like MultiActionController's invokeNamedMethod. For 
example, an AbstractFormController subclass would still override 
processFormSubmission or showForm as normal, but then as needed would be 
able to invoke something like invokeNamedMethod in those methods... Or 
it could manually get a resolved method, and use it as a command name, etc.
