jquery tools overlay, how to keep mask when switching overlays

I have a simple problem with 2 overlays. One overlay is triggered from (and by) the other overlay. As only one overlay can be active at any one time, correctly so, overlay number 1 that triggered 2 closes. However, it takes the mask with it and hence overlay 2 appears without the mask. How can I switch between 2 overlays without the mask disappearing?

The code, overlay 1

$("button[rel*=busy]").overlay({     

    api: true , 
    mask: {
        maskId: 'defaultMask' ,
        color: null
    },
    effect: 'apple',

    onLoad: function() {

        $.post( 'ajax_file_here.php' ,
            { var: something } ,
            function( data ){                

                if( data.status == 'confirm' ) {

                    confirmOverlay();

                } else {

                    errorOverlay();

                }              

            } ,
            'json' );

    } ,
    closeOnClick: false ,
    closeOnEsc: false ,
    close: '.noClose'       

});

And overlay 2

var errOverlayObject = $('#error_overlay').overlay({

    api: true,      
    mask: {
        maskId: 'defaultMask' ,
        color: null
    },
    effect: "apple"

});

function errorOverlay() {

    errOverlayObject.load();

}

As you can see there is also a confirm version of the second overlay, but that works identical to the error one.

I hope you do not mind but I created my own simplified example. Hopefully you will be able to adapt this to your situation.

There is a little bit of flicker between the dialogue boxes (due to the animation effect) but the mask stays in place. I imagine you could remove the flickering by adjusting the animation effect settings - I suspect you could do something in the overlay's onBeforeLoad method but I'm not exactly sure what.

               msk = this.getMask();
               msk.css('display','block');
               $(nextId).css('z-index', '9999');
            }
        }
    },
    closeOnClick: false,
    onBeforeLoad: function(){
        var id = this.getOverlay().attr('id');
        if(id == 'box2'|| id == 'box3'){
               // need to put something here to avoid flicker
               //
           // this.getConf().mask.startOpacity = 0.8; 
        }
    }
});

});

I hope this helps.

I think an easier way would be to

.overlay({
   mask: { color: '#000', opacity: '.60' },
   onLoad: function(){
       var t = $.mask;
       if(!t.isLoaded()){
            t.load();
            var ov = this.getOverlay();
            ov.css('z-index', '9999');
       }
   }
});

You can add "closeSpeed: 0" into mask configuration of the first overlay and it will work. For example:

    $('#login_overlay').overlay({
        top:'center',
        mask: {
            color: '#666',
            closeSpeed: 0,
            opacity: 0.5
        }
    });

An alternative is to handle separately the mask: the overlay is created without a mask, and the mask is activated separately.

Your first overlay would require a setup such as:

$(selector).overlay({ 
    ..., 
    onBeforeLoad: function(){
                       $(document).mask('#222'); 
                       closeMask=true;
                  },
    onClose: function(){
                       if (closeMask) $.mask.close();
                  }
);

Then, in order to show the second overlay, you set the closeMask variable to false. Obviously, the second overlay must hide the mask on close.
