I have some dominoDocument being cached, and being submited later together with other datasource. It always give me java.lang.NullPointerException, eventhough all values are present. Feels like there is hidden parameters determines if dominoDoc is still valid for submission. It works when I use dominoDoc.restoreWrappedDocument then dominoDoc.save(), took a look at the method restoreWrappedDocument, but since it involes BackendBride, its not something I do understand. anyone having experience with caching dominoDoc, and face similar problem? is restoreWrappedDocument documented feature which can be put into production?
