I thought it meant that once you have a known order of
parameter loading that you can rely on that order: in
the example given it seems like they're referring to
the ability to know modelClass's type, hence once
you've reached the setPrimaryKey method you know
enough to retrieve an appropriate instance of
modelClass.

Without ordering you'd need to use Preparable (well,
assuming a params -> prepare stack) to retrieve the
instance, because only then would you have complete
information (implementation and primary key).

Can someone enlighten me on the following excerpt from the

Apache Struts 2 Documentation
Parameters Interceptor

"Similiarily it's possible to use action.setPrimaryKey() property set call
to actually load the model class from persistent storage. Without any
assumption on parameter order you have to use patterns like 'Preparable'."
