extension of the standard form updatedesign()

Hello,

I have added a custom control LogisticsPostalAddress_WarehouseOnly to the standard form LogisticsPostalAddress by means of the form extension. Then I'd like to extend the standard form method updateDesign() like that

1st approach

[ExtensionOf(formstr(LogisticsPostalAddress))]
public final class LogisticsPostalAddressForm_Extension
{
    public void updateDesign()
    {
        FormBuildDesign formBuildDesign_WOOM = this.form().design();
        FormBuildCheckBoxControl wareHouseOnlyCBCtrl;

        wareHouseOnlyCBCtrl = formBuildDesign.control('LogisticsPostalAddress_WarehouseOnly');

        next updateDesign();

        switch (callerTableId)
        {
            case tableNum(CustTable):
                wareHouseOnlyCBCtrl.visible(true);
                break;
        }
    }

}

2nd approach. I put Autodeclaraton property of my custom control to Yes

ExtensionOf(formstr(LogisticsPostalAddress))]
public final class LogisticsPostalAddressForm_Extension
{
    public void updateDesign()
    {
        next updateDesign();

        switch (callerTableId)
        {
            case tableNum(CustTable):
                LogisticsPostalAddress_WarehouseOnly_WOOM.visible(true);
                break;
        }
    }

}

IN the 1st approach on this line I get null object reference on this line because control object wareHouseOnlyCBCtrl doesn't come. It's null. It's not fetched. formBuildDesign object is initialised and looks good.

wareHouseOnlyCBCtrl = formBuildDesign.control('LogisticsPostalAddress_WarehouseOnly');

the same goes with 2nd approach

How can I fix this please or what I'm mixing up?

Thank you.
