SelectOneMenu Problem

[daniel.camargo]

Hi,

Primefaces 3.0.M1 is really nice!

I've had only a small problem with the SelectOneMenu component (p:selectOneMenu).

I created a list of SelectItems and the first item on the list has a null value as shown below:

Code: Select all

List<SelectItem> items = new ArrayList<SelectItem>();
items.add(new SelectItem(null,  " ")); // <-- HERE is the problem
for (Enum e : type.getEnumConstants()) {
	items.add(new SelectItem(e,  e.name()));
}

I had a NullPointerException here:

Code: Select all

public String getSelectedLabel(FacesContext context, SelectOneMenu menu, List<SelectItem> items) {
		Object value = menu.getValue();
        String label = "&nbsp;";    //null display

        if(value == null) {
            if(!items.isEmpty())
                label = items.get(0).getLabel();
            else
                label = "&nbsp;";
        } else {
            for(SelectItem item : items) {
                if(item.getValue().equals(value)) { \\ <-- HERE I get a NullPointerException
                    label = item.getLabel();
                    break;
                }
            }
        }

        return label;
}

Is this really abnormal or I should use another way to get a blank option as the first option on the menu?

Hi, you can use the noSelectionOption with the appropriate text, but this
doesn't get selected, it's not totally clear if this is what you want:

Code: Select all

<h:selectOneMenu value="#{...}"
  <f:selectItem itemLabel=" - Select One - "noSelectionOption="true"/>
  <f:selectItems value="#{...}"/>
</h:selectOneMenu>
