[Collective-commerce] How to reinstall PloneMall without losing data?

[Giovanni T. <to...@un...>]

Hi,
in order to install a new version of Archetypes, I've uninstalled PloneMall 
and related products from a Plone site.
When trying ro reinstall, I got an error in installing PloneMallRegistry.
After removing PloneMall Categories and Items, I was again able to install 
all the suite.
Should'nt be possible to uninstall-install PloneMall without losing the 
data, as with many other products?
I did'nt take a copy of the error log; but, if useful I could re-create the 
situation.

Thanks in advance, Giovanni Toffoli
