Subject: Re: preparable vs modelDriven
I don't think you are strictly conveying the intended usage, when you
say that the getModel() method will 'later' return the model. It depends
how your interceptor stack is ordered. In the docs, it explicitly says
Is my understanding correct that Preparable and ModelDriven are 2 different ways
of doing the same thing, or are they complementary in any way?
After reading up on the website there are a few questions that spring to mind.
* ModelDriven: how do I get hold of my model during my action methods?

They *could* be used to do the same thing, but IMO Preparable is more
general-purpose than ModelDriven, and

don't want to get getModel() again, because that will retrieve another
instance
of the entity and not the one that was populated by struts.

Struts will by default populate parameters in your action, if you use
ModelDriven, then you can supply the object that will be populated
instead of the action. Implementing preparable will make struts call
prepare() before the action is executed, or prepareX() before X() is
executed. They are just

I thought I'd quickly describe my usages and opinions of Preparable and
ModelDriven in case it helps any one:
- As Dave described, I also prefer to keep my prepare logic with the
main code because it's easier for others to understand.
- I do use Preparable in the cases where
