Subject [validator] arg0-arg3 elements need name attribute to display mes sage?
Date Sun, 08 Jun 2003 13:47:01 GMT
I've been doing some messing around with the Validator and ran into an issue
I haven't seen mentioned on the list yet. I'm using 2 day old nightly builds
of Struts and commons-validator. Now, this is my first time trying out the
validator so I could be doing something wrong as well.

Anyway from all the examples that I have seen, and postings on the list,
this is how to define a validator for a form/field:

<form name="testForm">
	<field property="name" 
	<arg0 key=""/>
	<field property="value" 
	<arg0 key="testform.value"/>

Now, validation DOES happen, however the message keys (and I only have one
bundle) "" and "testform.value" are not used when a validation
occurs. Instead I get: "null is required". The only way I was able to get
the proper message key to work, was to specify the arg* elements like this:

	<arg0 name="required" key=""/>

In other words, I have to reference the validator name being used in the
arg* in order for the message to resolve. This is something that I haven't
seen mentioned anywhere in the existing documentation, books, or on the
list. Is it a bug or a new requirement? This happens with all Validator form
types, and my own "Dyna" form class.
