I'm pretty sure the array inst var of your WeakOrderedColleciton is no more a WeakArray but a simple Array.
Yes, indeed, it is a normal Array and that cought my attention. But since I have no idea about Weak stuff...I also noticed that WeakOrderedCollection is declared as:
OrderedCollection subclass: #WeakOrderedCollection instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Collections-Weak'
instead of using the #*weak*Subclass: ... message:
OrderedCollection *weak*Subclass: #WeakOrderedCollection instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Collections-Weak'
This is because Pharo's WeakOrderedCollection is broken...
Do you know a weak collection that is not broken in Pharo and let me do a addLast: ?
Every reference to Array from within OrderedCollection should be replaced with message send (self arrayType). See for example, OrderedCollection>>#grow
Thanks. I will check how many there are and try to fix them.

Hi guys. I am since yesterday trying to find something and I cannot. So at this point I need external eyes :) I have this little code:
anObject := ClassWith2Var new. sharedObject := ClassWith1Var new. sharedObject var1: 'nose'. anObject var1: Date today. anObject var2: sharedObject.
serializedObjects := FuelMareaSerializer new serializeAndWriteObject: anObject to: 'aFileName'. anObject := nil. sharedObject := nil.
3 timesRepeat: [Smalltalk garbageCollect]. serializedObjects inspect.
What is important here is that FuelMareaSerializer new serializeAndWriteObject: anObject to: 'aFileName' answers a WeakOrderedCollection with each object of the serialized graph (taking anObject as the root) Now, if I print the tempVar serializedObjects I see:
a WeakOrderedCollection(ClassWith1Var ClassWith2Var Date DateAndTime Duration a ClassWith1Var a ClassWith2Var 3 August 2011 2011-08-03T00:00:00+02:00 0:02:00:00 1:00:00:00 86400 2455777 'nose' 0
2011/8/3 Mariano Martinez Peck <marianopeck@gmail.com>: 7200)
WHYYYY?? why are all there if I put a nil to both, anObject and sharedObejct. This WeakOrderedCollection should be with all nils (except classes). Why are not being garbage collected?
If I explore, for example the tempVar sharedObejct, which is at serializedObjects at: 6 and then I put explore pointers I ONLY see the array of the WeakOrderedCollection pointing to it. I don't understand.
Any help is really appreaciated.
