Well....

State of actions (enabled, visible, checked, etc.) is updated periodically

when the application is idle.

In the same event actions are linked with the editor control.

It looks like DLLs do not have this actions update cycle, so actions in

DLL do not work.

You can try to simulate this cycle.

Add a timer to your form:

procedure TMyForm.Timer1Timer(Sender: TObject);

var i: Integer;

begin

for i := 0 to ComponentCount-1 do

if Components[i] is TrvAction then

TrvAction(Components[i]).UpdateTarget(RichViewEdit1);

end;

and assign to OnExecute of all RichViewActions on this form:

procedure TMyForm.rvActionExecute(Sender: TObject);

begin

(Sender as TAction).ExecuteTarget(RichViewEdit1);

end;
