Andi to send e-mail to Sally Cain requesting clarification and let her know our preference is to expose the actions even though nothing will happen if they are invoked.
Sally "recorded" this action but it was actually raised by Aaron Leventhal. Cynthia, please confirm that the behavior of native widgets is to expose the actions even if the widget is disabled. Then I will e-mail the PFWG about the issue.
Native behavior is inconsistent. WinForms sets the Default Action MSAA field to null, but callign dodefaultaction still triggers it. WPF leaves the field populated, but UIA invoke does not do anything. IE does not modify the field, and dodefaultaction does nothing. I recommned that we do not make a recommendation here, since the different UI frameworks behave differently.
