You will need to create attribute mappers for all column types that are not standard, and you need to tweak the code used to load meta data (primarily table names and index names) needed for evolve. What database/connectioncomponent are you planning to add support for?Thu, 11 Mar 2010 00:25:56 GMTJonas Hogstromhttp://www.capableobjects.com/apps/InstantForum414/Topic4986-4-1.aspxHi,<br>see there Eco Folder, Source, Eco.Persistence.XXXX.<br>Wed, 10 Mar 2010 08:07:12 GMTAlex Vedmedenkohttp://www.capableobjects.com/apps/InstantForum414/Topic4986-4-1.aspxHi,<br>Is there any documentation or samples on how to develop a custom persistence mapper?<br>ThankxWed, 10 Mar 2010 01:24:25 GMTebiexperts
