Hi,
Here I had two maps, one with cache and other without, with cache I use for
CRUD operations, and without cache for queries (long queries that returns many
objects), since for this two maps I use same classes, and this classes are used
in long transaction then must implement TimeStampable, but with the no cache
map I get follow exception:
org.exolab.castor.mapping.MappingException: A cache type other than none must
be used with >myapp.Person< as it implements TimeStampable.

...
to solve this Exception, I see the code of ClassMolder and the found the lines:
281: if ((_timeStampable) && (_cachetype != null) &&
(_cachetype.equalsIgnoreCase ("none"))) {
282: throw new MappingException
(Messages.format("persist.wrongCacheTypeSpecified", _name));
283: }
in my map files without cache I declared the tag cache-type like this:
<cache-type type="none"/>
that is causing the Exception, analysing the line 281, (_cachetype != null),
then if I remove this declaration from my no cache map, I no more get
Exceptions, and the problem is solved, I can have same Class cached in one map
and dont in another.
But my doubt is because what this Exception is throw? I cant see the reason for
that.
Thanks
Clovis
