Hi, Issue 40261 is about TStrings.AddObject issueing 2 consecutive OnChange events (and in the first one the to be added object is unassigned when accessing Objects[] property) when using InsertObject, AddObject and AddPair. This is Delphi incompatible.
The patch attached to https://gitlab.com/freepascal.org/fpc/source/-/issues/40261#note_1406426712 fixes this at the expense of calling BeginUpdate/EndUpdate (and for that use a try..finally construct). I kindly ask for this patch to be reviewed by one of the devels. -- Bart _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
