AbtEventDependents in AbtCLDTAdditions is holding on to my closed windows

[Richard Sargent]

AbtEventDependents is a weak-keyed dictionary. The only keys it contains are GbtValueHolder instances which are only referenced from the window's dependencies. GbtValueHolder subclasses Object, so uses this mechanism to manage its dependents. That I understand.

But, it appears that such a structure will never get garbage collected because of these dependencies.

I must be doing something wrong, so what is it? What should I be doing when I close the window to release these dependencies?

It looks like #initializeAttributeConnections should be counterbalanced by a #releaseAttributeConnections

releaseAttributeConnections
    " Private - release my attribute connection dependencies. "

    self attributeConnections do: [:each | each release].

called from #release

release

    self releaseAttributeConnections.
    ^super release.

This appears to work for my scenario. Whether it works for "normal" attribute classes remains to be seen.

Instantiations, any comments or thoughts on this approach?

Thanks, Seth. That's all I could ask.
