[jira] [Commented] (WW-3695) XWorkConverter catch XWorkException so that the client application can't get the detail original error message

["Maurizio Cucchiara (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-3695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13138205#comment-13138205 ] 

Maurizio Cucchiara commented on WW-3695:
----------------------------------------

As you can see there is an {{handleConversionException}} which is delegated to manage this kind of condition (it adds conversion errors to the action context).
So, whenever an user add a value which causes a conversion error, if I understand correctly should add a conversion error, which triggers the input result.
I could be wrong, I probably didn't get you, could you provide a test case or a more detailed example?

> here try catch code "defaultTypeConverter.convertValue" so that it can not throw exception to outside.
> in some case,for example:
> when I transmit a param a bigInteger to Integer in a action.
> the program will run pass and ignore this exception,the outside program can't catch it ,so that can't find what cause the error.
> and it only print in log file:
> {noformat}
> com.opensymphony.xwork2.util.logging.commons.CommonsLogger.debug(72) | unable to convert value using type converter [com.opensymphony.xwork2.conversion.impl.XWorkBasicConverter]
> Overflow or underflow casting: "3322333330" into class java.lang.Long - [unknown location]
> {noformat}
> and we need to find this  error message in large debug log message;
>  
> I think, throw this exception and not catch it here,and change log level from debug to error when print this message will better,isn't it ?
