prepopulate checkboxes in a success view
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
Code:
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
Code:
<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
Code:
<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:
Code:
<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!
