I've to look at what happens more closely, since now I've some clicks "lost", in the sense that when I push the command's link, its execution is not visible, although launched. I know that the execution is launched, since I tracked this down to GRPharoPlatform >> seasideCallbackMarker (as said before, the execution of this command includes calls to other components). It appears that in theses cases, #seasideCallbackMarker finds and returns a context, that of PRContext >> activationCallback. However, the #call: remains ineffective in the sense that the control is not passed to the new component!? Later, Regards, Reza
