Hi,

is there any way I can get Hibernate to Map:

Map<String,Set<String>> genericSets;

to a table like:

ID parentId;
String mapKey;
String setEntry;

so we might have rows like this:

1, foo, fooentry1
1, foo, fooentry2
1, bar, barentry1
2, foo, fooentry1
2, foo, fooentry2

This would enable me to write efficient SQL to perform counts on fooentryX etc and link back to the Parent without an extra linking table.
