<p class="MsoNormal">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>
