AFAIK Struts2 tries to set a new value to an object if it's currently null.
E.g. a new value for "person.address.street" should be set in a request.
If "person" is created in the prepare() method and if the action uses an
paramsPrepareParams stack then Struts2 tries to create the person object
in the first params run. Which doesn't make much sense in this case
because person will be created later by the action.
In the project I'm working on we don't have a setPerson method in the
action so a new value can't be set from the outside.
And we're using an interface for Person so S2 doesn't know what to create.
Havn't found a way to turn the behaviour off, though.

We would like to turn off the autowiring completly.
I understand that this is not really anything to do with STRUTS2, but
since it seems to be set via the STRUTS Spring plugin
I thought you guys would know.

Re: Spring autowiring null values
Spring autowiring (is autowiring by name the default?) isn't related to
XWork at all AFAIK.
Can you be a bit more specific about what behavior you're seeing
contrasted against what you'd prefer?
I mean, you can set Spring's default wiring to something else or turn
it off altogether.

Especially null values?
We use Spring to set up our actions to ease the integration of
hibernate, but we do not want Spring to set default values when
property is null.
Can this be turned off ?
I have tried <constant name="xwork.NullHandler.createNullObjects"
value="false"/> but this does not seem to be respected in all cases.
