Rene Gielen commented on WW-3318:
---------------------------------
I think I see your point here of taking a fail fast approach in production,
similar to the use of "assert" statements in production code.
Your usecase seems to make sense, and we should consider what are the technical
implications to support it. Changing the behavior of the combination of devMode
and throwExceptionOnFailure seems to be easy achievable, yet we have to
consider if changing this behavior would break existing code for other user.
And still, some people might want to retain the current behavior to have
devMode as kind of a master switch for different setup profiles.
That said, we might want to think of another property like, let's say,
globalExceptionPropagation=true/false (maybe a really bad name, any suggestion
appreciated) - this would override any combination of devMode and
throwExceptionOnFailure if true, thus propagating failure exceptions in any
environment.

> Key: WW-3318
> URL: https://issues.apache.org/jira/browse/WW-3318
> Project: Struts 2
> Issue Type: Bug
> Components: Value Stack
> Affects Versions: 2.1.8
> Reporter: Andreas Krüger
> Assignee: Lukasz Lenart
> Fix For: 2.2.x
>
>
> Setup:
> struts.el.throwExceptionOnFailure=true in struts.properties
> In the value stack, there is no object which has any property "xxx"
> The JSP has <s:property value="xxx == null ? 'Not yet determined' : xxx" />
> Expected behaviour: As the property xxx is not defined, this should throw an
> exception.
> Behaviour seen: The string "Not yet determined" gets inserted into the HTML
> output as if nothing were wrong.
