Hi everyone,

I have a model framework that I am currently testing using WOUnit. For the Account EO I have a unit test to ensure that the email attribute is valid before saving. That worked fine until I started changing the code to be localizable.

I have a ValidationTemplate.strings in the framework under Resources -> English.lproj -> ValidationTemplate.strings

Values in the template

{
"EmailFormatException" = "A valid <b>@@displayNameForProperty@@</b> is required.";
"Account.email.EmailFormatException" = "<b>@@displayNameForProperty@@</b> must be a valid email address.";
}

Properties set:

# Localization

er.extensions.ERXLocalizer.defaultLanguage=English

er.extensions.ERXLocalizer.fileNamesToWatch=("Localizable.strings","ValidationTemplate.strings")

er.extensions.ERXLocalizer.availableLanguages=(English)

er.extensions.ERXLocalizer.frameworkSearchPath=(app,ERDirectToWeb,ERExtensions)

er.extensions.ERXLocalizer.useLocalizedFormatters=true

Validation code:

public String validateEmail(String newEmail) {

ERXValidationFactory factory = ERXValidationFactory.defaultFactory();

if (!Account.isValidEmail(newEmail)) {

ERXValidationException exception = factory.createCustomException(this, Account.EMAIL_KEY, newEmail, "EmailFormatException");

throw exception;

}

return newEmail;

}

When I run the unit test for the Account EO I get a stack trace in the logs:

- Undefined Validation Template entity "Account" property "EmailFormatException" type "CustomMethodException" target language "English"

java.lang.Throwable

It looks to me as if maybe the validation template cannot be found but I'm not certain what would cause that. Possibly there is something I need to load before running the test? Does anyone know what that might be?
