<ul><li><strong>Resolution</strong> set to <i>wontfix</i></li><li><strong>Status</strong> changed from <i>Open</i> to <i>Closed</i></li></ul><p>This is intended behaviour. The extent of a composer map is independent of the main map extent. If you want the composer map to adapt to a changed main map extent, you need to press 'set to map canvas extent' button in the composer map widget.<br />Because both extents are different, it is e.g. possible to have multiple composer maps in one printout showing different parts of the map or to have an overview map at a different scale.</p>
