java.beans.beancontext.BeanContextChildSupport.addVetoableChangeListener()
Add a VetoableChangeListener for a specific property. The same listener object may be added more than once. For each property, the listener will be invoked the number of times it was added for that property. If name or vcl is null, no exception is thrown and no action is taken. @param name The name of the property to listen on @param vcl The VetoableChangeListener to be added
