Hi,
So I cleaned it up a little bit...
I created as assignment that has methods like this:
protected NSDictionary<String, Object> resolveBindings(D2WContext context,
NSDictionary bindings) {
NSMutableDictionary<String, Object> resolvedBindings = new
NSMutableDictionary<String, Object>();
for(Object key : bindings.allKeys()) {
String aKey = (String) key;
Object value = context.valueForKeyPath((String)
bindings.objectForKey(aKey));
if(value != null) {
resolvedBindings.takeValueForKey(value, aKey);
}
}
return resolvedBindings;
}
@Override
public Object fireNow(D2WContext c) {
Object result = null;
Object value = value();
if(value != null && value instanceof NSDictionary) {
result = resolveBindings(c, (NSDictionary) value);
}
return result;
}
And then I updated my restritedChoiceList method to look like this:
EOEditingContext ec = ERXEC.newEditingContext();
EOEntity entity = d2wContext().entity();
EORelationship relationship = entity.relationshipNamed((String)
d2wContext().valueForKey("propertyKey"));
NSDictionary bindings =
(NSDictionary)d2wContext().valueForKey("restrictingFetchSpecificationBindings");
ec.lock();
try {
return EOUtilities.objectsWithFetchSpecificationAndBindings(ec,
relationship.destinationEntity().name(), fetchSpecName,
bindings);
} finally {
ec.unlock();
}
And it works...
Any comments/advice would be appreciated!
Thanks,
Johnny
