Ah you have created add/remove track functions, nice. I found that by using the _replace<br>
function I can simulate add/remove, but I will switch over to the new functions once<br>
there's a new release of OGM.<br></blockquote><div><br></div><div>Yeah, the new API should be a little more consistent. </div><div><br></div><div> * The map has an internal 'GPS track' (an OsmGpsMapTrack object).

I just hooked up the OsmGpsMap defined maps into foxtrotGPS and I noticed that setting the<br>
map-source property does not redraw the map. It will use the new source though when<br>
forcing a redraw by using zoom in or out.<br></blockquote><div><br></div><div>This is a bug.</div><div><br></div><div>John</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
