Subject [jira] Updated: (WW-3306) Null value accepted from action property, but not model property when throwExceptionOnFailure=true

Andreas Krüger updated WW-3306:
-------------------------------

    Attachment: WW3306.zip

Sorry about the goof!

I found out our application's problem was concerned with class inheritance rather than
with properties of properties.

Also, there are some issues when using OGNL method calls that return nulls.

I enclose a minimal test suite. This time as a ZIP archive, for better convenience.

> 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.
