Guy Veraghtert closed JBSEAM-880.
---------------------------------

    Resolution: Done

Pete, things work fine now when adding a noSelectionLabel.

FYI, if NO noSelectionLabel is added, Sun RI 1.2 generates following stacktrace:

java.lang.IllegalArgumentException: Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectOne(projectMenu).  Found null.
	at com.sun.faces.renderkit.RenderKitUtils.getSelectItems(RenderKitUtils.java:357)
	at com.sun.faces.renderkit.html_basic.MenuRenderer.getOptionNumber(MenuRenderer.java:675)
	at com.sun.faces.renderkit.html_basic.MenuRenderer.renderSelect(MenuRenderer.java:793)
	at com.sun.faces.renderkit.html_basic.MenuRenderer.encodeEnd(MenuRenderer.java:335)
