Ti.PageFlip only can show primitive views?

Hi,

I try to build a pageflip based app with tiles in the pages. It seems as if I can only add primitive UI elements like views, imageviews, maps, label, but no hierarchy of it.

Here my code of pageflip:

var pages = [];
for (var i = 0; i < 7; i++) {
        pages[i] = require('ui/page_with_tiles')(i + 1);
}
var pageflip = PageFlip.createView({
    transition : PageFlip.TRANSITION_FLIP,
    transitionDuration : 0.3,
    pages : pages
});
win.add(pageflip);

and here the content of module:

var Module = function(_page) {
    var self = Ti.UI.createView({
        backgroundColor : '#78C6E4'
    });
    self.add(Ti.UI.createImageView({/* some params*/}));
    self.add(Ti.UI.createLabel({
        bottom : 10,
        height : Ti.UI.SIZE,
        text : 'Page: ' +_page,
        color : 'white'
    }));
    return self;
};
module.exports = Module;

After starting of app I see only the background color of 'self', Label and image view I cannot see. But on the rotating spinner in status bar I see,the app retrieves images from net …

I found 'MPFlipViewController' as iOS Library. This module works with child views.Is there a Titanium transformation?

Cheers!
