Subject Re: Creating multiple datamaps on the fly
Date Thu, 04 Jun 2009 11:21:54 GMT

I'm not sure that I correctly understood your problem, but cloning datamap
is definitely possible. Alas, I don't know about any ready methods for that.
You can either clone DataMap manually (i.e. create new map with new name,
copy properties from original map, put there entities etc. with new names
and then attach it to domain) or clone whole datamap via serialization and
then change names of its "entries". Sort of second way is implemented in
modeler's PasteAction.paste(...). Note that entity names must be unique in
whole DataDomain.
