[Zope] Zope/DCO2 and CHAR[1] fields not working.

Hi, I've only recently started playing with Zope, and esp. the new DCO2 Oracle product, but far I'm liking it very much. However, I've come accross a problem when trying to access certain fields in our databases, we have several char[1] fields, used for storing 'Y'/'N' and various other "single character identifiers", however, when issueing an SQL statement such as "select user_flag_1 from staff" I get the following error: Error, exceptions.TypeError: no type converter registered for type SQLT_AFC I'm using the binary release of the oracle product running under Zope 2.3/NT . Does anyone here have any hints and/or solutions I could try to getting this resolved? Mark -- Sig goes here.
