Show validation X besign fields if validation at entity level failed

Question

Hi,
We are doing all validation at the entity level by throwing sth like the following
when a condition mandatory field is not filled in (i.e we override the validateEntity method).
<pre>
return new AttrSetValException(MetaObjectBase.TYP_ATTRIBUTE, OurMessageBundle.class, "27014", fieldName, fieldName, fieldValue);
</pre>
Everything is cool, as the validation message is showing up at the top. However, we need to put a X besides the field too when this failed, much like what you see when you use <af:convertDateTime tag...> .
How to do this? Is it possible? We have defined our own error handle class and faces life cycle as doc by Oracle.
I though by throwing AttrSetValException with fieldname="name" and my input text on jspx has id="name" will do the trick but it doesn't.
Help is much appreciated.

See an example of custom-validation rule that can be applied to an entity/attribute.
It's oracle.jbo.server.rules.JboGenericValidator and the source is in BC4J/src/bc4jaddinsrc.zip
Also I've verified on JDev 903 Preview release that creating a new 'validationrule' in the project editor and applying it to 'entity' at entity level does work. validateValue() is called with 'entity' as the input Object.
