-----------------------------------------
Summary: Allow customization of validation messages by passing
arguments to the validator for the message
Key: WW-4208
URL: https://issues.apache.org/jira/browse/WW-4208
Project: Struts 2
Issue Type: Improvement
Components: Annotations, XML Validators
Affects Versions: 2.3.15.2
Reporter: Jose L Martinez-Avial
As of today the key/messages used by the annotated validators do not allow to
receive custom arguments, since only the parameters defined by the annotation
can be used. In order to improve that I suggest to add a parameter keyArgs to
the validation annotations so it will be passed to the OGNL evaluator when it
evaluates the key provided in the annotation. That way the following would be
possible:
{code}
@Validations(
requiredStrings =
{@RequiredStringValidator(type = ValidatorType.SIMPLE,
keyArgs={"email","one","two"}
}
)
{code}
Then the key/message could be something like this:
{code}
validation-error.mandatory = The field ${getText(keyArgs[0])} is mandatory
email= E-mail
{code}
And the result would be
{code}
The field E-mail is mandatory
{code}
It would allow to customize the message even further than it allows now. I
suppose it would need to be implemented also in xml validations, but I haven't
used them, so I don't what would be needed for that.
