SelectItems only renders SelectItemGroup objects and not SelectItem objects inside

[Jan Bols]

I have a form like the following:

<h:form>  
        <h:selectManyCheckbox>
                <f:selectItems value="#{test.items1}"/>
        </h:selectManyCheckbox>
</h:form>
The test.items1 is an ArrayList with 2 SelectItemGroup objects. Each one  
containing 3 SelectItem objects:

public class Test {
        private Collection items1;      
        
        public Test() {
                items1 = new ArrayList(2);
                
                SelectItem options1[] = {
                        new SelectItem("200", "Duke's Quarterly", ""),
                        new SelectItem("202", "Duke's Diet and Exercise Journal", 
""),
                };
                SelectItem options2[] = {
                        new SelectItem("201", "Innovator's Almanac", ""),
                        new SelectItem("203", "Random Ramblings", ""),
                };
                        
                SelectItemGroup g1 = new SelectItemGroup("Duke's", null, true, 
options1);
		SelectItemGroup g2 = new SelectItemGroup("General Interest", null,  
false, options2);
                items1.add(g1);
                items1.add(g2); 
        }
        
        public Collection getItems1() {
                return items1;
        }

        public void setItems1(Collection group1) {
                this.items1 = group1;
        }
}

When I render this form I see 2 checkboxes with the labels of the  
selectItemGroup objects. The SelectItem objects aren't rendered. When I  
change selectManyCheckbox to selectManyListBox everything renders OK.   
When I change to the JSF RI everything renders OK aswell.

Is this a bug?

I'm using the nightly built myfaces-20050531.
