prepopulate checkboxes in a success view

[Rossen]

Hi,

I have a page with a drop-down list which allows a user to choose the type of music he likes. After choosing and submitting, I want to display the available cd's of this type of music from the data base, in checkboxes form in another page. But I am not able to find out how to do it, and when choosing and submitting, I'm getting: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'command' available as request attribute

My controller

BuyController.java

public class BuyController extends SimpleFormController {

	private ProductManager productManager;

	public ModelAndView onSubmit(Object command) throws ServletException {

		String type = ((ProductType) command).getType();

		Map<String, Object> myModel = new HashMap<String, Object>();
		myModel.put("products", this.productManager.readType(type));

		return new ModelAndView("buySearch", "model", myModel);
	}


	public ProductManager getProductManager() {
		return productManager;
	}

	public void setProductManager(ProductManager productManager) {
		this.productManager = productManager;
	}

The relevant part of my form view:

buy.jsp

<form:form method="POST" commandName="productType">
<form:select path="type">
<form:option value="NONE" label="--Select please"/> 
<form:option value="Classic"/>
<form:option value="Rock"/>
<form:option value="Pop"/>
<form:option value="Jazz"/>
</form:select>

<input type="submit" value="OK">
<form:errors path="tipus" cssClass="error" />
</form:form>

My success view:

buySearch.jsp

<form:form>
<c:forEach items="${model.products}" var="prod"> 
<form:checkbox path="model.products" value="${prod.title}"/>
<c:out value="${prod.title}"/> 
<c:out value="${prod.price}"/> 
</c:forEach>
</form:form>

I'm getting the exception at the line "<form:checkbox path...."


my bean configuration:

<bean name="/buy.htm" class="eMusicalWorld.web.BuyController">
		<property name="sessionForm" value="true" />
		<property name="commandName" value="productType" />
		<property name="commandClass" value="eMusicalWorld.service.ProductType" />
		<property name="validator">
			<bean class="eMusicalWorld.service.ProductTypeValidator" />
		</property>
		<property name="formView" value="buy" />
		<property name="successView" value="buySearch" />
		<property name="productManager" ref="productManager" />
	</bean>

Any idea why am I getting this exception and how to solve it?

Thanks in advance!
