what does woody's multivaluefield. getvalue return???

[Christina]

it seems that as a 'multi' value field it should return an array. But in its class definition, it seems that it only return one object! does this object any special? Would anybody give me some idea why??? Many Thanks!!!!    getValue public Object getValue() Description copied from interface: Widget Returns the value of the widget. For some widgets (notably ContainerWidgets) this may not make sense, those should then simply return null here. Object having a value, but whose value is invalid, will return org.apache.cocoon.woody.Constants#INVALID_VALUE. Specified by: getValue in interface Widget Overrides: getValue in class AbstractWidget
