<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am not sure if this is an issue with GeoExt and the
gx_mappanel, Mapfish, or something else I’ve done, but as the
Subject says when my map is first loaded more than initial base map is loaded.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I think I am triggering the load of the other base map layer
when I build my layer tree. I’ve got 2 Google layers and one GeoTiff for
base maps.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Doing some debugging, I’ve added a
“loadstart” to the GeoTiff layer. This event is fired if I add my
ExtJS TreePanel to the viewport. If I just create the TreePanel, but
don’t add it to the viewport, the layer is not loaded. This only seems to
be happening with this one base map layer. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Another oddity, and I am again not sure if this is a GeoExt
or OpenLayers issue, is with the Google Layers. Looking at the openlayers
example: <a href="http://openlayers.org/dev/examples/google.html">http://openlayers.org/dev/examples/google.html</a><o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>the net traffic shows only the Physical Map data is coming
back. In my map, I get the Physical data as well as some queries for the
regular Google Map/roads. There are just a few tiles for the road map, but I
have no idea why those are getting requested.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The physical map requests have this format: <a
