Binding object in a selectMenu

[Dennis John]

Hello, I am trying to bind an object to the value property of a selectOneMenu but cannot get it working. It does work, however, when I bind an object of type Long.

I get a conversion error where it tells me I cannot convert object@address to null. Any thoughts on if this is possible and what I am doing wrong? Here is my code.

jsp page
<h:selectOneMenu value="#{projectManager.customerId}" valueChangeListener="#{projectManager.getProjects}" onchange="submit()">
<f:selectItems value="#{projectManager.customers}"/>
</h:selectOneMenu>

  
public SelectItem[] getCustomers() throws Exception {
logger.trace("entering getCustomers");
Collection customers = null;
try {
customers = customerService.getAll();
} catch (Exception e) {
e.printStackTrace();
throw e;
}
SelectItem[] items = new SelectItem[customers.size()];
Iterator i = customers.iterator();
for (int index=0; index < customers.size();index++) {
Customer c = (Customer)i.next();
items[index] = new SelectItem(new Long(c.getId()), c.getName());
}
logger.trace("exiting getCustomers");
return items;
}

Sorry, that is the code that works. The code that doesn't looks like this.

jsp page
<h:selectOneMenu value="#{projectManager.customer}" valueChangeListener="#{projectManager.getProjects}" onchange="submit()">
<f:selectItems value="#{projectManager.customers}"/>
</h:selectOneMenu>

  
 
public SelectItem[] getCustomers() throws Exception {
logger.trace("entering getCustomers");
Collection customers = null;
try {
customers = customerService.getAll();
} catch (Exception e) {
e.printStackTrace();
throw e;
}
SelectItem[] items = new SelectItem[customers.size()];
Iterator i = customers.iterator();
for (int index=0; index < customers.size();index++) {
Customer c = (Customer)i.next();
items[index] = new SelectItem(c, c.getName());
}
logger.trace("exiting getCustomers");
return items;
}
