CRM2011-MultiForm: Display default form based on the Optionset/Lookup field values on the form.

  var programlookup = new Array();
    programlookup = Xrm.Page.getAttribute("msft_programid").getValue();

    if (programlookup != null)
    {

        var name = programlookup[0].name;
        var guid = programlookup[0].id;
        var entType = programlookup[0].entityType;
        // alert(Xrm.Page.ui.formSelector.getCurrentItem().getLabel());

        if (Xrm.Page.ui.formSelector.getCurrentItem() != null)
        {
            var formlabel = Xrm.Page.ui.formSelector.getCurrentItem().getLabel();
            if (formlabel != name)
            {
                var items = Xrm.Page.ui.formSelector.items.get();
                for (var i in items)
                {
                    var item = items[i];
                    var itemId = item.getId();
                    var itemLabel = item.getLabel()

                    if (itemLabel == name)
                    {
                        var attributes = Xrm.Page.data.entity.attributes.get();
                        for (var j in attributes)
                            attributes[j].setSubmitMode("never");
                        item.navigate();
                    }

                }
            }
        }
    }

Disadvantages: 

1. Performance(Form will load twice if last opened form is not same as field value)

2. On load page will blink

3. Make optionset/lookup field readonly so that user can't change the values
