Are you asking if you can change/morph your datastore values from Boolean to String? If so, you'll have to make a copy so the new property is added in older records. Or do a conversion when getting a record.
You can add a persistance variable at any time, and the property going forward will be added to the record. To deal with previous records that have nothing null stored, then add logic to check for that. When I make adjustments to the datastore persistance classes, I increment my version before deployment. I've run across errors deploying the same version with new datastore enhancements with new class variables. Hope that helps, Brandon Donnelson http://gwt-examples.googlecode.com http://c.gawkat.com -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
