Peter Mahoney commented on RF-980:
----------------------------------

Using 3.1.1, when I try to delete the last node I get the following exception:

javax.faces.FacesException: java.lang.IllegalArgumentException: fromIndex(0) > toIndex(-1)
	at org.richfaces.renderkit.TreeRendererBase.encodeAjaxChildren(TreeRendererBase.java:510)
	at org.ajax4jsf.component.UIDataAdaptor.encodeAjaxChild(UIDataAdaptor.java:397)
...
