Using Struts Validator on Map-backed ActionForms

["Cordingley, Charles" <Ch...@rbs.co.uk>]

Hi,

I am trying to use the Struts Validator to generate Javascript validation on
a Map-backed action form, but I keep getting "type is null or not an object"
javascript error (I am using Struts 1.1). Non map-backed properties on the
form work fine.

In the JSP I am creating text boxes using:

<html:text style="WIDTH: 75px; text-align: right"
property='<%="volume("+act.getActivityID()+")"%>'
value='<%=""+scenAct.getActivityVolume()%>'/>

and have this method on the action form to get it:

public void setVolume(String key, Object value) {
   volumes.put(key, value);
}

In the validation.xml I have tried:

<field property="volume()"
   depends="required">
   <arg0 key=""/>
</field>

and:

<field property="volume()"
   depends="required">
   <arg0 key=""/>
</field>

but both result in the error.

Does anyone know how to do this?

Thanks,
Charles.

I don't think this is legal, i.e., you can not have a bracket inside of property
attribute:

	<field property="volume()"

You form should have the getter method for getVolume().
