Adam Winer commented on MYFACES-1140:
-------------------------------------

Note the JSF 1.2 solution, which is to use a "label" attribute on the component with the error, not the clientID.

>          URL: http://issues.apache.org/jira/browse/MYFACES-1140
>      Project: MyFaces
>         Type: New Feature
>   Components: Tomahawk
>     Versions: Nightly
>  Environment: JBoss  4.0.3, XP
>     Reporter: Dave
>     Priority: Critical

>
> A Java property map, a collection of name/value pairs,  is renederd as a dataTable, and user can change values.
> Two columns: property name and property value. Values are rendered in a subview as different components based on their types.
> For validation errors or conversion errors, the generated IDs are used, for example,
>     "_idJsp155": value is required
> <outputLabel for=".."> does not work in this case.
> An optional attribute for UIData component like
>     replaceIdForMessages="#{row.propertyName}"
>  would solve the problem.
>  Its value can bind to a back bean property, supporting localization automatically.
> It is more efficient than <outputLabel for="..."> that requires findComponent() to search the tree.
