The problem is somehow related to the way my page and component are
hooked up/working.
For testing purposes I now create the Breadcrumb list in the component
itself, simply returning a created list on the fly whenever
getBreadCrumbs() is called. This works as expected!!!
Strange thing is that via passing the 'model' to the component via a
page binding the same thing doesn't work. This must be a bug?!
