Musachy Barroso commented on WW-2723:
-------------------------------------
Also, the parameters are always String arrays, so when there is an exception,
printing the values in the array would be better than the cryptic
[Ljava.lang.String;@12dcb8c thing.
> Provide debug information about which methods where matched/invoked by OGNL

> Key: WW-2723
> URL: https://issues.apache.org/struts/browse/WW-2723
> Project: Struts 2
> Issue Type: Improvement
> Components: Expression Language
> Affects Versions: 2.0.11.2, 2.1.2
> Reporter: Jeromy Evans
> Priority: Minor
> Fix For: Future
>
>
> It would be helpful if developers could enable debug messages where Struts2
> displays the methods that were invoked when getting or setting a property.
> eg. rather than "user.firstName", see that it invoked action.getUser() then
> User.getFirstName()
> This will help debugging mismatched property names (eg. isUser(), getUser,
> getuser()) and especially help developers understand that, for example,
> getUser() must be invoked prior to setFirstName().
