Antonio
In my cocoon.xconf I have:
<forms-validators>
<!-- new-style validators -->
<validator
class="org.apache.cocoon.forms.validation.impl.JavaScriptValidatorBuilder"
name="javascript"/>
...
</forms-validators>
Is this what you meant?
My validation is for a repeater row: the XML now looks like:
<fd:repeater id="dsdata" size="5">
<fd:validation>
<fd:javascript>
return true;
</fd:javascript>
</fd:validation>
<fd:widgets>
...
The stack trace looks like:

Nope. Sorry for my previous mail. It works in 2.1.5. I though the
problem was 2 javascript statements in the same line.
Question, do you have the javascript validator defined in your cocoon.xconf?
Have you tried to use:
<fd:validation>
<fd:javascript>
return true;
</fd:javascript>
</fd:validation>
To check if this works? Can you post the NPE stack trace?
Best Regards,
Antonio Gallardo.
