If you use lazarus 0.9.31 from trunk, then read
http://wiki.lazarus.freepascal.org/Lazarus_0.99.0_release_notes#TCustomPageControl.2FTPageControl.OnPageChanged_were_removed
That page contains breaking changes, so read that before submitting a
bug report.
IMO the recent rename was bad, because the current TCustomTabControl is
implemented as a TPageControl, incompatible with a (Delphi) TTabControl.
I had hoped that the widgetset interface would allow to implement simple
tabbed controls (without pages), and derive paged controls in the LCL,
but nothing happened in that direction :-(
Most ComCtrls suffer from the duplicate storage of the items, in the
widgets and in the controls. I'd be happy with the way how Delphi
manages all items, using a *temporary* item list *only* while no widget
exists - i.e. when such a control is loaded from a resource, or when it
must be recreated later. On nowadays machines it will do no harm to
refer to the properties stored in the widgets, which will be up-to-date
and consistent all the time.
