Error while Populating html:options with validations!!

[Vikas]

Hi Friends,

I am getting a peculiar problem while populating the "<html:select" options with validations and interestingly the request isn't passed to even Action Class!! Whereas when I am not mapping the validation in validation.xml file, the jsp page works fine otherwise it throws me the exception as follows:

******************************************************************

My piece of code in Action class is as follows:-

ArrayList brandValues=new ArrayList();
try {

BrandSelectVO brandVO = new BrandSelectVO();
BrandSelectForm brandForm = (BrandSelectForm) form;

brands=BrandSelectDao.getBrand(getDataSource(request));

Iterator it=brands.iterator();
while(it.hasNext())
{
brandVO=(BrandSelectVO)it.next();
brandValues.add(new LabelValueBean(brandVO.getName(), String.valueOf(brandVO.getBrandID())));
}
request.setAttribute("brandValues",brandValues);
target = "success";
*****************************************************************

My JSP Reads like this:-
<html:form action="/BrandSelect" onsubmit="return validateBrandSelectForm(this);">
<html:select property="collectionSelect" multiple="true" styleClass="large">
<html ptions collection="brandValues" property="value" labelProperty="label"/>
</html:select>
</html:form>
<html:javascript formName="brandSelectForm"/>
*************************************************************
Validation.xml is as follows:-

<formset>

<!-- brandSelectForm form -->
<form name="brandSelectForm">
<field property="collectionSelect" depends="required">
<arg key="brandSelectForm.collectionSelect"/>
</field>
</form>

</formset>
*****************************************************************

Thanks in advance

Hello All,

Just now found out the answer of how to validate html ptions when we get the error "Cannot find bean under name clmTypeList"

Make an Actionform class "Testng1" where the ArrayList is populated.

  
public class Testng1 {

private ArrayList clms=null;
 
public ArrayList getClms()
  {
  String clmtypecode=" ";
  ArrayList clmTypeList = new ArrayList();
  
clmTypeList.add(new LabelValueBean(clmtypecode, clmtypecode));
clmTypeList.add(new LabelValueBean("123", "123"));
clmTypeList.add(new LabelValueBean("456", "456"));
clmTypeList.add(new LabelValueBean("789", "789"));
clmTypeList.add(new LabelValueBean("101", "101"));
clmTypeList.add(new LabelValueBean("201", "201"));
clmTypeList.add(new LabelValueBean("301", "301"));

return clmTypeList;
  }
}

In the Action Class put

Testng1 t1 = new Testng1();
request.getSession().setAttribute("t1", t1);

In the jsp file file put

<bean :mrgreen: efine id="clmTypeList" name="t1" 
       property="clms" type="java.util.ArrayList"/>
<html:select name="FormatFormBean" property="clmType">
  <html :-o	 ptions  collection="clmTypeList"   property="value"
                 labelProperty="label"  />
</html:select>

It should work.

Thanks,
Lk.
