> Key: WW-4318
> URL: https://issues.apache.org/jira/browse/WW-4318
> Project: Struts 2
> Issue Type: Bug
> Components: Value Stack
> Affects Versions: 2.3.16.1
> Reporter: Brendan Le Ny
> Assignee: Lukasz Lenart
> Priority: Trivial
> Labels: logging
> Fix For: 2.3.18
>
> Attachments: WW-4318.patch

> Original Estimate: 5m
> Remaining Estimate: 5m
>
> Most of the time, the logging message printed by OgnlValueStack class is useless because it doesn't show the value that causes the problem.
> Exemple log:
> {quote}
> 2014/03/20 02:23:28 WARN (CommonsLogger.java:64) warn Error setting expression 'myIntField' with value '[Ljava.lang.String;@55227e4a'
> ognl.MethodFailedException: Method "setMyIntField" failed for object fr.my.company.MyAction@df39b8b4 [java.lang.NoSuchMethodException: fr.my.company.MyAction@df39b8b4.setMyIntField([Ljava.lang.String;)]
> {quote}
> I can't find the reason because toString() is on a array show '[Ljava.lang.String;@55227e4a' but i would like to see the actual value in the array.
> The exact same problem is fixed right in the method above the buggy one: the trivial patch is included.
