Form Validation with multi-lingual fields ?

Hello,


We have a container with 2 fields :

   - An Image Field (type FieldTypes.FILE)
   - An ImageAlt Field (type FieldTypes.SMALLTEXT)


We want to check the following validation rule : "The ImageAlt field is
mandatory only if the Image field is not null"

Code of the JavaBean associated to the ImageAlt field :

 public JahiaMltHelper getImageAlt()
{
return getJahiaMultiLanguageField("ImageAlt");
}


Here is an extract of the Jakarta validation Xml file :

<field property="imageAlt" depends="validwhen">
 <msg name="validwhen" key="errors.required"/>
 <arg0 key="ImageAlt" resource="false"/>
 <var>
 <var-name>test</var-name>
 <var-value>((image == null) or (*this* != null))</var-value>
 </var>
</field>
This code doesn't work.




If the ImageAlt definition is changed to a
FieldTypes.SMALLTEXT_SHARED_LANGtype, the rule works fine with the
following modification in the validation JavaBean :
 public String getImageAlt()
{
return getJahiaField("ImageAlt");
}

In this special case all works fine. But we need multi lingual fields !!!


Thank's for your help.


Best regards...
