objective c - Core Data managedObjectContext not being updated with UI changes -


i have encountered strange problem when making updates core data objects using ui controls bound core data nsmanagedobjects.

symptoms follows: - outlineview displays list of hierarchical objects - detailed view shows data fields selected object, these include text fields, dates etc. - when updates made in detailed view these reflected in outlineview (e.g. diplayname used in outlineview). - when save changes managedobjectcontext tells me there no changes saved. reason ui not letting context know things have changed. - given bindings done in ib assume changes in ui automatically reflected in managedobjectcontext - reason 1 of fields seems result in context recognising changes have been made not others. 1 field happens popup list containing objects entity in core data database.

if has inkling on causing - there way monitor when ui changes made, example changing text in text field, , whether these changes propagated managedobjects.

edit found problem - reason had changed of properties @dynamic @synthesize in objective-c classes core data entities. breaking things !

the iboutlets need hooked callbacks changes known. don't report changes unless hook up. though textfield.text != oldtext, doesn't matter unless take update, save entity, see if recognizes

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
