Subject [jira] [Created] (WW-4193) OGNL WARN msg in log when user enters invalid data
Date Sat, 07 Sep 2013 12:37:51 GMT
Christoph Nenning created WW-4193:

             Summary: OGNL WARN msg in log when user  enters invalid data
                 Key: WW-4193
             Project: Struts 2
          Issue Type: Bug
          Components: Expression Language, Value Stack
    Affects Versions:
            Reporter: Christoph Nenning
            Priority: Minor

When a user enters a invalid value, the framework logs a WARN msg with stacktrace. Even when
dev mode is disabled.

For example:
- an Action with an int as member
- a form with a text field for that int
- user enters a string

The framework tries to find a setter for that member (which is successful) and tries to set
the value (which fails because the setter has wrong parameter type)

Then a stracktrace is logged as WARN.

It is a valid use case that users enter invalid data and no stracktrace should be logged (at
least not when dev mode is disabled).
