hi guys,

so I'm using validator.xml to check my form.
In short: If the user will send a check - don't check for creditcard info. but if the checkBox is not checked- validate the nameOfuser on creditCard.

I need an 'if statment' and I do the following with validwhen:

struts-config.xml

<form-property 	name="check"  	  			 type="java.lang.String"  initial=""/>
<form-property 	name="nameOnCreditCard" 	 type="java.lang.String"  initial=""/>   

jsp:

		<td>
			<html:checkbox property="check" value="true">Will send a check</html:checkbox><br>
			<html:errors property="check" />	
		</td>

validation.xml

            <field property="nameOnCreditCard" depends="validwhen">
            <arg0   key="error.nameOnCreditCard.required"/>   
		        <var>
		          <var-name>test</var-name>
		          <var-value>((check == false) or (*this* != null))</var-value>
		        </var>           
            </field>           

so basically I'm asking this: if the user clicks the checkBox - will send a check - DO NOT CHECK for nameOnCreditCard (if it's empty - that's ok)

for somereason, any combination I'm trying doesn't work!!!

((check == false) or (*this* != null))
((check == true) or (*this* != null))
(check == false) 
(check == true) 
((check == 'false' ) or (*this* != null))
((check == 'true') or (*this* != null))
((check == '1 ) or (*this* != null))
((check == 1) or (*this* != null))

in other words, even if the checkbox is clicked or not (and it's working i checked) the nameOnCreditCard has an empty error message (suppose to show an error message if the checkBox is not clicked)

anyone?
