Hello list! I have an occasionally occurring problem which I can not reproduce but regularly meet in usage logs. Editing context fails to save changes and reports:
java.lang.IllegalStateException: rowDiffsForAttributes: snapshot in com.webobjects.eoaccess.EODatabaseOperation {_dbSnapshot = {}; ..... } does not contain value for attribute named colorNoWeight with snapshot key: colorNoWeight it also happens for different objects mentioning another attributes, but as I see a common situation is that _dbSnapshot value is empty dictionary so no matter what attribute is mentioned. Why could this happen? Object in question was surely in database, not just created or deleted. Also sometimes I get NullPointerException when accessing attributes described as not null, so it seems like object was not initialized on fetch. May it be because these objects were fetched or created and saved in child editing context and after that used (with EOUtilities.localInstanceOfObject() ) in parent ? Once I got reproducible malfunction working with temporary EOEditingContext. EOUtilities.localInstanceOfObject(ec, this) was returning an objects with all attributes set to null whereas original object was fine and was stored in database even before app launch. try { boolean cache = ec.hasChanges() if(cache) { ec = new EOEditingContext(); ec.lock(); AutoItog ai = (AutoItog)EOUtilities.localInstanceOfObject(ec, this); course = (EduCourse)EOUtilities.localInstanceOfObject(ec, course); result = calculator().collectRelated(course, ai, !namedFlags().flagForKey("runningTotal"),true); } else { ec.lock(); result = calculator().collectRelated(course, this, !namedFlags().flagForKey("runningTotal"),true); } ec.saveChanges(); if(cache) result = EOUtilities.localInstancesOfObjects(editingContext(), result); } catch (RuntimeException e) { logger.log(LogLevel.WARNING,"Error collecting related", new Object[] {this,e}); } finally { ec.unlock(); } _______________________________________________ Do not post admin requests to the list.
