Web - Actions order doesn't work for the Unspecified category

Hello,
I would like to ask you, for a web application, how can I specify a specific order for a few simpleactions that I have created.
Let's say that I have three simpleactions and each simpleaction 1 to 3 (button1, button2, button3) is created by a different viewcontroller (1 to 3), now I would like to specify which one goes first, second and third in the row.
Thanking you in advance.
Regards,
Vakis
Steps to Reproduce:
<ActionDesign>
          <ActionToContainerMapping>
               <ActionContainer ID="Unspecified">
                    <ActionLink ActionID="1" Index="3" />
                    <ActionLink ActionID="2" Index="2" />
                    <ActionLink ActionID="3" Index="1" />
               </ActionContainer>
          </ActionToContainerMapping>
     </ActionDesign>

        protected override void Dispose(bool disposing) {
            if (disposing && (components != null)) {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
        #region Component Designer generated code

        private void InitializeComponent() {
            this.components = new System.ComponentModel.Container();
            this.simpleAction1 = new DevExpress.ExpressApp.Actions.SimpleAction(this.components);
            this.simpleAction2 = new DevExpress.ExpressApp.Actions.SimpleAction(this.components);
            this.simpleAction3 = new DevExpress.ExpressApp.Actions.SimpleAction(this.components);
