Musachy Barroso commented on WW-3306:
-------------------------------------

Confirmed. The problem is that the code that check for the missing property 
only checks the actions, if the action is ModelDriven, it doesn't check the 
model. I also found what it seems like another bug, this code in xwork:

 for (Object o : root) {
                if (o instanceof ActionSupport || 
o.getClass().getSimpleName().endsWith("Action")) {
                    try {
                        findAvailableProperties(o.getClass(), expr, 
availableProperties, null);
                    } catch (IntrospectionException ise) {
                        // ignore
                    }
                }
            }

it should check all objects in the stack, not only "o instanceof ActionSupport 
|| o.getClass().getSimpleName().endsWith("Action")"

> Null value accepted from action property, but not model property when 
> throwExceptionOnFailure=true

>             Project: Struts 2
>          Issue Type: Bug
>          Components: Value Stack
>    Affects Versions: 2.2.0
>            Reporter: Andreas Krüger
>
> In this project, we experiment with setting 
> struts.el.throwExceptionOnFailure=true to catch errors.
> We use <s:property value="myprop" /> in our JSP.
> Occasionally, the property thus referenced is null. We want struts to insert 
> an empty string in that case.
> This it duely does, when either struts.el.throwExceptionOnFailure=false or 
> when the property is from an action object.
> However, if the property is from a model object and 
> struts.el.throwExceptionOnFailure=true, this bombs out.
