I have noticed that I couldn't add empty String as SelectItem to rich:comboBox.

After I do that, it stops showing all values for this combo box.

For example, I have the following Java code to populate combo box with values:

        private List<SelectItem> templateOwnersList =

new Vector<SelectItem>();

        private String templateOwner;

        ...

//  templateOwnersList.add(new SelectItem("", ""));

templateOwnersList = new Vector<SelectItem>();

final List<String> owners = templateMgr.getTemplateOwners();

for ( final String curOwner : owners)

{

     templateOwnersList.add(new SelectItem(curOwner, curOwner));

}

Commented line makes all added values unavailable.

Front end is as follows:

<

rich:comboBox id="owner" width="160" value="#{qtBeanParam.templateOwner}" enableManualInput="false" >

Would appreciate, if somebody would explain, if it is indeed a bug.
