Hi All

If you look at the Expresso CVS, I have already checked in a
modification to the following classes


com.jcorporate.expresso.ext.taglib.ElementCollection.java

	setting tag attribute `type="nested"' iterates
	through all generic controller elements.
	effectively calling the method
		`public Vector ControllerElement#getNested()'


com.jcorporate.expresso.ext.struts.taglib.logic.ExIterateTag

	setting tag attribute `property="nested"' iterates
	through all generic controller elements.
	effectively calling the method
		`public Vector ControllerElement#getNested()'

This is a long standing bugfix.
