I have seen that in apps that violate the commandments: http://wiki.wocommunity.org/pages/viewpage.action?pageId=1050329 If relationships are going missing and you are using nested ECs you may want to try ec.setRetainsRegisteredObjects(true) There's a known bug where EOs can be GCed which can result in nulls coming from required relationships. Nobody has managed to fix it in wonder yet. Ramsey _______________________________________________ Do not post admin requests to the list. They will be ignored.
