ASF GitHub Bot commented on WW-685:

aleksandr-m opened a new pull request #215: WW-685 Add generic type conversion 
error message
URL: https://github.com/apache/struts/pull/215
   Another one for 2.6. :)
   Note: Because of the `Object` in conversion errors map (`Map<String, Object> 
conversionErrors`) there is no type check when switching to `Map<String, 
ConversionData>`, which can lead to some errors.
   Note: The `ConversionData` can be improved and used later in other places.

> To change the default message "invalid field value for field "xxx"", 
> you can put this line in the Action.properties
> > invalid.fieldvalue.[propertyName]
> But will be useful if there is a way to do a generic custom message to any 
> type? For example a custom message for Dates, double, boolean, etc:
> > invalid.fieldvalue.For_All_Dates=This is not a valid date.
> I don´t know how to implement it, but could be like this:
> > invalid.fieldvalue.java.lang.Integer=This is not a valid Number.
> > invalid.fieldvalue.java.util.Date=This is not a valid Date.
> -------------
> I tried the following examples, but them doesn´t work:
> invalid.fieldvalue.*=Invalid Date.
>  and
> invalid.fieldvalue.[*]=Invalid Date.
