Associating error messages with fields that are map keys

[danielm]

If I have a form object which has a Map, I can set map values using the syntax myMap['key'] for the field name, the question is, how can I associate an error message with this field using the Errors class (ie what would the field name be)?

Cheers

Hello Daniel,

to link an error message to a field held in a Map, you just have to name the field name the same way as you do in your view if you're using JSTL.

For instance, you can use :

errors.rejectValue("myMap[key]", "errorMessage");

Your command object must have the getter/setter for the 'myMap' attribute and 'key' must be valid.

Hope this helps
