Customizing Stripes Messages - Stripes...and Java Web Development is Fun Again - page 124

The following table shows the defaultScope and errorName for each
built-in validation and type converter:

minlength=N validation.minlength valueTooShort

maxlength=N validation.maxlength valueTooLong

minvalue=N validation.minvalue valueBelowMinimum

maxvalue=N validation.maxvalue valueAboveMaximum

mask="M" validation.mask valueDoesNotMatch

expression="E" validation.expression valueFailedExpression

EmailTypeConverter converter.email invalidEmail

EnumeratedTypeConverter converter.enum notAnEnumeratedValue

Number TypeConverter 1 converter.number invalidNumber

converter.type 2 Number TypeConverter outOfRange

PercentageTypeConverter converter.number invalidNumber

PercentageTypeConverter converter.type outOfRange

To change the text of an error message, change the corresponding entry
in the StripesResources.properties file, or add a new entry. We can use
a key that is as specific or as general as we want. For example, the
following

stripesbook.action.ContactFormActionBean.contact.email.valueNotPresent

is most specific, while the following

validation.required.valueNotPresent

is most general. We can use the {0} and {1} tokens to include the field
label and the value entered by the user in the error message text.

Certain validators and type converters provide additional parameters,
starting at {2} , as shown here in the table on the next page.

1. Number refers to each number type converter: ByteTypeConverter , IntegerTypeConverter ,
and so on.
2. type refers to the number type, as in converter.byte , converter.integer , and so on.
