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.
