Hi all,
I'm using WO 5.3 and only ERExtensions from Wonder.
I've just started getting an odd error now when I try to save my
EditingContext that I've never gotten before. The full stack trace is
below, but here's the basics, formatted for easier reading:
<WorkerThread0> Server exception:
rowDiffsForAttributes: snapshot in
com.webobjects.eoaccess.EODatabaseOperation {
_dbSnapshot = {};
_entity = "BillOfMaterial";
_newRow = {
isActive = false;
mustBeBalanced = false;
partId = <com.webobjects.foundation.NSKeyValueCoding$Null>;
routingDescription = "Preform Homestyle 240/1oz Chocolate Chip, MMA
BOM";
isDefault = false;
productionSequence = 0.000000;
partQuantity = 1.000000; };
_object = "Preform Homestyle 240/1oz Chocolate Chip, MMA BOM";
_globalID = _EOIntegralKeyGlobalID[BillOfMaterial
(java.lang.Long)1138];
_databaseOperator = "EODatabaseUpdateOperator";
} does not contain value for attribute named billOfMaterialTypeId with
snapshot key: billOfMaterialTypeId
I see several problems with this:
1) _dbSnapshot is completely empty! This object is in the DB, so it
should have a dbSnapshot, right?
2) The only change to the EO this is referring to _should be_ that the
partId is being set to null by this object being removed from the Part-
>> BillOfMaterial relationship. Part "owns" BillOfMaterial, so this
object should be in the process of being deleted.
3) The list of attributes in the _newRow dictionary isn't complete. It
really doesn't contain the billOfMaterialTypeId attribute or several
others. Why?!
billOfMaterialTypeId is a non-class attribute in the Model that is a
FK for a toOne relationship. According to the API for
EODatabaseOperation newRow, and I'm assuming _newRow, are supposed
to contain all non-derived attributes, including non-class ones like
PKs and FKs.
Any ideas as to what is going on?!
