[jira] Commented: (BEANUTILS-41) Provide better error message for "No value specified"

    [ https://issues.apache.org/jira/browse/BEANUTILS-41?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12754123#action_12754123 ] 

Ralf Hauser commented on BEANUTILS-41:
--------------------------------------

commons-beanutils-1.8.0.jar has only a slight improvement:

It now says: <<No value specified for 'Date'>> but if you still have more than one Date-type field, error hunting is still very inefficient...

> Provide better error message for "No value specified"

> Suggestion:
> 1) cite the propName and the bean className
>    this probably implies that the interface
>      org.apache.commons.beanutils.Converter.convert(Class type, Object value)
>    is extended to

>                                         String propName, String beanClassName)
> 2) also cite the concerned class name (probably java.sql.Date) 
> 3) mention that there is the possibility to use a default value
