Hi All,

Im getting a strange error where WO claims to not know what the entity for an object is.

Here's the code :

EOEditingContext ec = new EOEditingContext();

AuditLog newLog = (AuditLog) EOUtilities.createAndInsertInstance(ec,"AuditLog");

newLog.setPerson((Person)EOUtilities.localInstanceOfObject(ec,((Session)session()).currentPerson()));

newLog.setEntityName("TestEntity");

newLog.setIpAddress(((Session)session()).getIPAddress(context().request()));

newLog.setAttributeName("TestAttribute");

newLog.setNewValue("NewValue");

newLog.setOldValue("OldValue");

ec.saveChanges();

Here's the error :

Error:

java.lang.IllegalStateException: Unable to find entity for object {values = {attributeName = "TestAttribute"; newValue = "NewValue"; person = ""; message = ; when = 2006-06-29 07:01:34 Etc/GMT; ipAddress = "130.130.72.73"; entityName = "TestEntity"; oldValue = "OldValue"; }; this = ">"; }

Reason:

Unable to find entity for object {values = {attributeName = "TestAttribute"; newValue = "NewValue"; person = "<Researcher 36083b (com.webobjects.eoaccess.EOAccessFaultHandler _EOIntegralKeyGlobalID[Researcher (java.math.BigDecimal)1541])>"; message = <com.webobjects.foundation.NSKeyValueCoding$Null>; when = 2006-06-29 07:01:34 Etc/GMT; ipAddress = "130.130.72.73"; entityName = "TestEntity"; oldValue = "OldValue"; }; this = "<AuditLog f4b610 <EOTemporaryGlobalID: 0 0 -126 -126 72 73 0 0 -49 100 1 0 0 0 1 12 30 -105 -72 30 25 96 -16 -12>>"; }

AuditLog is an entity in the model file ( both are part of a framework ). AuditLog extends EOGenericRecord.

Any ideas on why this is happening and how to fix it ?
