Description

Have the ability to pass a date format string to the validator so that the dates will format how the developer desires when a validation error is hit. I have included an example of how I worked around the problem. Feel free to use this as a starting point.

Example:

public class CustomMinimumDateValidator extends AbstractValidator<Date> {

private final Date minimum;
private final String format;

public CustomMinimumDateValidator(Date minimum, String format)

{ this.minimum = minimum; this.format = format; }

@Override
protected void onValidate(IValidatable<Date> validatable) {
Date value = validatable.getValue();
if (value.before(minimum))

{ error(validatable); }

}

@Override
protected Map<String, Object> variablesMap(IValidatable<Date> validatable)

{ final Map<String, Object> map = super.variablesMap(validatable); SimpleDateFormat sdf = new SimpleDateFormat(format); String minimumString = sdf.format(minimum); map.put("mindate", minimumString); map.put("inputdate", sdf.format(validatable.getValue())); return map; }

@Override
protected String resourceKey()

{ return "CustomMinimumDateValidator.minimum"; }

}
