Hi,

is there a way to get an OrderedSet out of allInstances()? I get a new order each time I call it.

Hi

allInstances()->asOrderedSet() gives you an OrderedSet, but you probably
want a sensible ordering too, so something more like

NamedElement.allInstances()->sortedBy(name)

may be better.

Hi,

my problem is that allInstances is already a set and has a different order each time it is called. Putting it into an ordered set could help while the program is running as I would get a temporary order. The problem is that I need to have the same order even if I restart the program in between. Ordering by something like a name could help. I think I will walk the model manually and collect the instances.

Thanks!!

Ralph
