class EDOSelectedModel

extends MVCBoolModel

This class encapsulates the data model for the flag indicating whether an editable domain object (EDO) is selected from a set of EDOs in an EDOHolderModel. One and only one EDO can be selected at a time. This model also keeps track of which EDO is selected. If a new EDOHolder is selected (thus loading new data) "this" gets reset to false (i.e nothing selected).
