Okay, so there's ERXEOControlUtilities.clearSnapshotForRelationshipNamed[InDatabase] (which saves me a few lines of code :) but which doesn't appear to be auto-called from anywhere(?). Would it be useful for there to be a property that does something like this automatically?

What I've now got in my ERXGenericRecord subclass now is:
public void awakeFromFetch( EOEditingContext editingContext )
{
super.awakeFromFetch( editingContext );

if ( editingContext == EOSharedEditingContext.defaultSharedEditingContext()
&& ISHApplication .ishApplication ().hasFetchedInitialSharedRecordsForEntity( entityName() ) )
{
for ( Enumeration< ? > en = classDescription().toOneRelationshipKeys().objectEnumerator(); en.hasMoreElements(); )
{
String key = en.nextElement().toString();
EORelationship inverseRelationship = entity().relationshipNamed( key ).inverseRelationship();
if ( inverseRelationship != null && inverseRelationship.isToMany() )
{
EOEnterpriseObject eo = ( EOEnterpriseObject )valueForKey( key );
if ( eo != null )
// this next line covers Anjo's code from the wiki page below
ERXEOControlUtilities.clearSnapshotForRelationshipNamed( eo, inverseRelationship.name() );
}
}
}
}


This is working fine. Is there any suggestions on anything else that might need doing for completeness?

Yes - that's exactly the sort of stuff I'm trying to solve.

Question: is there some property in Wonder that does this automatically?

Hi there,

just wondering ... how would I go about clearing the faults for certain toMany relationships of an object. i.e., I'm iterating through certain toMany keys and I want to obtain the faults without firing them (best case scenario) and then clear them so that they are refreshed.

Any suggestions?

with regards, --
