[JIRA]

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

                 Key: WW-3306
                 URL: https://issues.apache.org/struts/browse/WW-3306
             Project: Struts 2
          Issue Type: Bug
          Components: Value Stack
    Affects Versions: 2.1.8
            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.
