validation annotation message attribute required even if using key attribute
----------------------------------------------------------------------------
Key: WW-2263
URL: https://issues.apache.org/struts/browse/WW-2263
Project: Struts 2
Issue Type: Bug
Components: Validation
Affects Versions: 2.0.9
Environment: Debian Linux
Reporter: chad michael davis
This "bug" is about a quirky interface to validations using annotations. In
the XML, the message element can contain the text of the message in its body,
or omit the body and use key attribute to name the key into the resource
bundles for retrieving the message.
Under annotations, the message attribute is always required. Seems like you
should be able to specify a key and drop the message attribute but you can't.
To specify a key you must use the key attribute ( note, key and message are
sibling level attributes of the annotation itself; this is different from the
xml ) such as follows:
@EmailValidator(type = ValidatorType.FIELD, key="email.invalid", message="Email
no good.")
In this annotation, I still have a message specified, as a back up I guess.
But if I try to remove it altogether, the equivalent of what i do in XML with
the following:
<field-validator type="requiredstring">
<message key="username.required"/>
</field-validator>
Then it blows up. i guess this isn't a bug, but it seems kind of odd, forcing
the user to specify a message text that won't be used ( a default message will
be provided in the form of the key string itself if the properties file is
missing, right? ), and its clearly inconsistent between the XML and the
annotations
