Hi Antoni,
I added the list in CC.
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 :
getParams: function(node) {
return {'service': 'WMS', 'request': 'GetCapabilities'};
},
You could try to override this method :
GeoExt.tree.WMSCapabilitiesLoader.prototype.getParams = function(node) {
return {'service': 'WMS', 'request': 'GetCapabilities', 'version':
'1.1.1'};
};
HTH,
Alexandre

Hi Alexander,
I’ve made the test, and GML as plain text in a file parsed by
OpenLayers.Format.WMSCapabilities get a layer with minScale to “infinity”.
Notice that this property becomes to WMS version 1.1.1, and the server
response is version 1.3.0 by default, not our case because OpenLayers
use 1.1.1 if not provided.
What do you think it could be the best solution?
Best regards,
Antoni

Hi Antoni,
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 :
<ScaleHint min="39.597980" max="Infinity"></ScaleHint>
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) :
var resolutions = new Array(numZoomLevels);
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.
Best regards,
Alexandre

Hi list,
I’m testing WMSBrowser example in my production server and it
works fine calling some WMS servers but in some cases, it doesn’t.
Open http://www.icc.cat/WMSBrowser/examples/WMSBrowserICC.html (it
uses EPSG:23031) and try the following WMS servers:
A.OK: http://sima.gencat.cat/DMAH_ws/SIMA_OGC/MapServer/WMSServer?
B.NOT OK:
http://siurana.igc.cat/arcgis/services/geotermia/amplitud_termica/MapServer/WMSServer
Firebug shows an “invalid array length” produced in
WMSBrowserTreePanel.js line 111, when layer must be added to
previewMap...
Maybe somebody could light me.
