Well, I changed to cascade to test out that theory, and it seems to
get past those steps, but I'm getting a more esoteric error now for
each delete. Does this sound familiar?
An Exception occured while trying to save the information:
com.webobjects.eoaccess.EOGeneralAdaptorException: The attribute
NeededByEOF0 should be assigned a Number, but the value was the String
"20"
Its always the same line with simply String "20 switching to "56" "14"
"66" "29" etc.
