There is already a check called requiredMandatoryLang, which does a global "in all mandatory languages" check before submission, but this is not what you need, because you don't simply want to set the field for all mandatory languages, but you want to set it mandatory only for those languages, where you have an image.

As far as I understand the standard validwhen check from Struts, it just checks the current language of the referred field, so this is also not enough.

You could try this:

In addition to the current validwhen check you could add a new validwhen and a method to your bean like this:

< field property = "imageAlt" depends = "validwhen" >
    < msg name = "validwhen" key = "errors.mandlang" />
    < arg0 key = "ImageAlt" resource = "false" />
    < var >
        < var-name > test </ var-name >   
        < var-value > imageAltMissingLang == null </ var-value >
    </ var >
</ field >

new method:

 public String getImageAltMissingLang() {
        StringBuffer missingLanguages = new StringBuffer();

        JahiaMltHelper imageMlt = getJahiaMultiLanguageField("Image");
        JahiaMltHelper imageAltMlt = getJahiaMultiLanguageField("ImageAlt");

        String[] imageTexts = imageMlt.getText();
        String[] imageLanguages = imageMlt.getLanguage();

        for (int i = 0; i < imageTexts.length; i++) {
            if (imageTexts[i] != null && imageTexts[i].length() > 0) {
                String imageAlt = imageAltMlt
                        .getText(imageLanguages[i]);
                if (imageAlt == null || imageAlt.length() == 0) {
                    missingLanguages.append(imageLanguages[i]);
                    missingLanguages.append(" ");
                }
            }
        }
        return missingLanguages.toString();
    }

I have not tested this yet, but I hope you understand the principal. You iterate through all languages of the image field and if it is set you check if the ImageAlt is set for the language. If it is not set you add the language to the returned String. If the returned String is not empty the message under the key "errors.mandlang" is displayed. You could also define a more fancy message and the missing languages as parameter to the message.

Let me know if it works, otherwise I will take a closer look and try to reproduce.
