Validation

[Mary Cole]

Hi,
I want to validate certain fields for required format and as Required.

I am using org.apache.struts.validator.DynaValidatorActionForm as the type for the deliveryForm in struts config.xml.

My field is a group of checkbox

 <html:multibox property="delivery.selectedReports"> 

and I iterate this. My JSP code is

 <logic:iterate name="deliveryForm" id="item" property="delivery.possibleOptions">
  <html:multibox property="delivery.selectedReports">
<bean1:write name="item" property="value" />
  </html:multibox>
<bean1:write name="item" property="label" /><br />
</logic:iterate>  

Delivery is defined as

<form-property name="delivery" type="com.company.user.dto.DeliveryPreferences"/> in struts config and possibleOptions is an array of LabelValueBean.


I have set up all the validations correctly in the validation.xml.

When I go to this page , the form gets displayed properly, but when I submit the form( to see if it validates the field), the form displays partially and thows an exception

 
javax.servlet.jsp.JspException: No collection found

at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:474) 

but in the JSp when I write the Javacode to extract the values,

 org.apache.struts.validator.DynaValidatorActionForm l = (org.apache.struts.validator.DynaValidatorActionForm)session.getAttribute("deliveryForm");
org.apache.struts.util.LabelValueBean[] loVal=(org.apache.struts.util.LabelValueBean[])(((com.company.user.dto.DeliveryPreferences)l.get("delivery")).getPossibleOptions());
for(int i=0;i<loVal.length;i++){
System.out.println(loVal[i]);
} 

I get all the values printed properly......I want to know where am wrong..... Thx in advance
