Facet blocks are not appearing, when indexed view block is called programmatically with views_embed_view
For now, i have fixed it, putting the facet blocks also in the page.tpl.php, for me in the first sidebar. I iterated all active facet blocks in the block table an d then displayed each one with this code:

        $block_facet = block_load($module, $delta);
        print render(_block_get_renderable_array( _block_render_blocks(array($block_facet))));
