<p>Hi all,</p>
<p><br>
</p>
<p>after working with WeakKeyDictionarys for months in SimulationStudio, I discovered (actually: Marcel pointed out to me) that dereferencing a key from such a dictionary does *not* remove the associated values automatically:</p>
<p><br>
</p>
<p></p>
<div>d := WeakKeyDictionary new.</div>
<div><span style="font-size: 12pt;">d at: Morph new put: 42.</span><br>
</div>
<div><span style="font-size: 12pt;"></span></div>
<div>d keys. "#()"</div>
<div>d instVarNamed: 'array'. "{nil->nil . nil . nil . nil . nil->42}"</div>
<br>
<p></p>

<div name="divtagdefaultwrapper" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:; margin:0">

<div class="_rp_T4" id="Item.MessagePartBody">I first need to send #finalizeValues to the dictionary to clean up the array.

<div class="_rp_T4" id="Item.MessagePartBody"><br>
</div>
<div class="_rp_T4" id="Item.MessagePartBody">Now my question is, is - or should be - every client of a WeakKeyDictionary <span style="font-size: 12pt;">expected to care about finalization themself, or should these dictionaries be added to a weak registry or
the finalization process of WeakArray automatically?</span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><br>
</span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;">The following would achieve that:</span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><br>
</span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><span>WeakArray addWeakDependent: d.</span><br>
</span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><span>Maybe one could also set up a WeakRegistry manually, but I didn't figure out yet how to do this.</span></span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><span><br>
</span></span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><span>Should I append this code to any of my code that creates a WeakKeyDictionary, or should this happen inside its constructor already?</span></span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><span><br>
</span></span></div>
<div class="_rp_T4" id="Item.MessagePartBody"><span style="font-size: 12pt;"><span>Best,</span></span></div>
