Hello;
I have this one working. But now I have implemented another
wotomanyrealationship. The structure is exactly the same ag the
mgtOfc except it is for training. when I try to load the page with
that wotomany on it I get the follow error trace.
dwtm

Great.
ToManyRelationship: WOToManyRelationship {
sourceEntityName = "Agents";
destinationDisplayKey = "orgs";
sourceObject = agent;
relationshipKey = "mgtOfc";
}
However it is a cominbation of all fields in the orgs entity that
are being displayed separated by commas and surrounded by curly
braces. So I set destinationDisplayKey to orgs.description
to get a more user friendly view. I get an error that
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException:
valueForKey(): lookup of unknown key: 'orgs.description'.
You need to set the destination display key as the key *from* the
objects found at "mgt0fc" rather than from your source object.
So that should be something like:
destinationDisplayKey = "org.description"; // i.e., it's a toOne
from your join record.
with regards,
