<div class="moz-cite-prefix">Hi Antoni,<br>
<br>
I added the list in CC.<br>
<br>
The tree uses the WMSCapabilitiesLoader to trigger the WMS
GetCapabilities requests. Looking at the code in GeoExt 1.1, is
parameters are returned by the getParams methos, which looks like
this :<br>
<br>
getParams: function(node) {<br>
return {'service': 'WMS', 'request': 'GetCapabilities'};<br>
},<br>
<br>
You could try to override this method :<br>
<br>
GeoExt.tree.WMSCapabilitiesLoader.prototype.getParams =
function(node) {<br>
return {'service': 'WMS', 'request': 'GetCapabilities',
'version': '1.1.1'};<br>
}; <br>

<p class="MsoNormal">Hi Antoni,<br>
<br>
I think I found what the issue is. If you take a look at
the capabilities returned by that WMS service, you'll notice
a "max" attribute equal to "Infinity" inside ScaleHint nodes
: <br>
<br>
<ScaleHint min="39.597980"
max="Infinity"></ScaleHint><br>
<br>
OpenLayers reads this and sets the layer minScale property
to "infinity". At some point, the number of zoom levels is
calculated using the min and max scales properties of the
layers, which ends up equalling to "infinity". This is the
line that, in the end, throws the error (in Layers.js, in
calculateResolutions) :<br>
<br>
var resolutions = new Array(numZoomLevels);<br>
<br>
numZoomLevels equals "infinity". I think you found a bug
in OpenLayers. Would you please try making a small example
using your capabilities GML returned (as plain text, in a
file) and use OpenLayers.Format.WMSCapabilities to read it
and see if the layer minScale property is equal to
"infinity" as well ? That would become a nice test-case to
reproduce the issue.<br>
<br>
Best regards,<br>
<br>
