I'm getting a crash in the following code:
public boolean is_unassigned () {
// editingContext ().refaultObject (this);
log.info ("is_unassigned " + this.groups ());
boolean result = true;
java.util.Enumeration <Group_Member> e = groups ().objectEnumerator
();
while (result && e.hasMoreElements ()) {
Group_Member gm = e.nextElement ();
if (gm.group ().parent_group () != null && gm.end_date () == null)
result = false;
}
return result;
}
caused by groups on line 5 being a _EOCheapCopyMutableArray. The
enclosing object for this method was originally created in another
editingContext (being Java client, in another window), so I suspect
something to do with the groups being in another (now gone) editing
context. It does not happen all the time though, only on the first
object created - if I restart the application, further objects can be
added without problem.
A fix that seems to work is the commented out line 'editingContext
().refaultObject (this);', but this seems to me like it is probably a
kludge making up for a problem elsewhere. Anything else I should be
looking out for?
The dump I get out is:
