But what does this have to do with the problem you mention in FreeAndNil ?
It's rebuilding a component tree, while part of the tree is still being
destroyed. That this will go wrong seems logical to me, but irrelevant to
FreeAndNil.
As you can see from the linked discussion,
currently implemented workaround involves FreeAndNil.
I can imagine a similar bug which might require FreeThenNil instead.
I didn't see any linked discussion in the indicated page.
All I can conclude from this page is that there is a bug in TAChart, most
likely returning children in GetChildren, which are in fact no longer there.
But that is just guesswork, and still I fail to see the link with FreeAndNil.
If I see things in mails like like
"This code is so complicated, I can not understand what is going on."
Then I automatically think "Badly written code" and therefore 'error-prone'.
But never mind.
Michael.
