This could be a bug in the memory datastore. I wouldn't be
surprised. Memory datastore was originally designed to be only used
for testing but was too handy to stay that way...
On closer reading of your message, I'm not sure entirely what you
mean. (sorry) You want to delete a feature and then add a feature
with the same ID? or when you add a feature it adds it as a feature
with the same ID?
Part of the API states that you cannot choose the ID of the features
you are adding. The datastore gets to determine that. That is why
the addFeatures method returns a set of Feature IDs. (All the
features that you added). Maybe it should be a list so you can
determine which fid goes with which feature... but that is another
discussion for the geotools list.

Hi!
I have discovered something fishy:
It is not possible to add a Feature to a MemoryDataStore if it has the
exact name as a Feature that once existed but was deleted (using the
standard uDig Feature deletion operation) at some time.
What works of course is always adding Features with a unique name over
time (never using names that have been used before, even if they were
deleted from the DataStore). It is strange to have to keep that in
mind
when adding new Features and deleting them from a MemoryDataStore
though.
