I've customised Deactivate button to add a few hide/show rules, before customising its CommandCore was set to Mscrm.Forms.Deactivate, after customising Command and CommandCore are pointing to my custom Command.
But that means I need somehow call Default Mscrm.Forms.Deactive command inside my custom command as Deactivate button no longer works, while hide/show rules are working.
Is there a way to either have button run 2 commands Core/NonCore or option to call a default command from custom one?
