All my HtmlSelectOneRadio's are broken with Seam 1.1 (worked

[ngeadah]

I know about the @SelectItems that is available and how that could be a potential solution, but I would instead like to understand why something that was working perfectly in Seam 1.0 is broken when I moved to 1.1.

I have a SFSB that exposes a List attribute. The getter populates that List and the contents of the list are displayed using an h:selectOneRadio with f:selectItems.

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("loginClient")
public class LoginClientBean implements LoginClient {
...
 private List<SelectItem> customerTypes;

 public List<SelectItem> getCustomerTypes() {
 customerTypes = new LinkedList<SelectItem>();
... Adding to customerTypes
 return customerTypes;
 }

 public void setCustomerTypes(List<SelectItem> customerTypes) {
 this.customerTypes = customerTypes;
 }

And the JSF:

<h:selectOneRadio id="customerType" value="#{loginClient.selectedCustomerType}" required="true">
<f:selectItems value="#{loginClient.customerTypes}" />
</h:selectOneRadio>

Upon submit, I now get a nasty exception:

java.lang.IllegalArgumentException: Value binding '#{userMaintenanceClient.usersSelectItems}'of UISelectItems with component-path {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /UserMaintenance.xhtml][Class: javax.faces.component.html.HtmlForm,Id: userMaintenance][Class: javax.faces.component.html.HtmlPanelGrid,Id: _id23][Class: javax.faces.component.html.HtmlPanelGroup,Id: _id24][Class: javax.faces.component.html.HtmlSelectOneRadio,Id: selectRadio][Class: javax.faces.component.UISelectItems,Id: _id25]} does not reference an Object of type SelectItem, SelectItem[], Collection or Map but of type : null

Worked just fine in Seam 1.0.1. Something must have changed in 1.1 to break this. Thanks for any insights.
