Brendan Le Ny created WW-4318:
---------------------------------
Summary: Logging message when OgnlValueStack fail to set
expression is cryptic most of the time
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
Priority: Trivial
Most of the time, the logging message printed by OgnlValueStack class is
useless because it doesn't show the value that cause de 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:
[email protected]([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.
