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>Alexandre<br><br><br>On 12-09-21 09:02 AM, Vidal, Antoni wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>Hi list,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I’m testing WMSBrowser example in my production server and it works fine calling some WMS servers but in some cases, it doesn’t.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Open <a href="http://www.icc.cat/WMSBrowser/examples/WMSBrowserICC.html">http://www.icc.cat/WMSBrowser/examples/WMSBrowserICC.html</a> (it uses EPSG:23031) and try the following WMS servers:<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>A.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>OK: <a href="http://sima.gencat.cat/DMAH_ws/SIMA_OGC/MapServer/WMSServer">http://sima.gencat.cat/DMAH_ws/SIMA_OGC/MapServer/WMSServer</a>? <o:p></o:p></p><p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>B.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>NOT OK: <a href="http://siurana.igc.cat/arcgis/services/geotermia/amplitud_termica/MapServer/WMSServer">http://siurana.igc.cat/arcgis/services/geotermia/amplitud_termica/MapServer/WMSServer</a> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Firebug shows an “invalid array length” produced in WMSBrowserTreePanel.js line 111, when layer must be added to previewMap...<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Maybe somebody could light me.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Regards,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#0D0D0D'>Antoni Vidal</span></b><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:gray'>Unitat d'Aplicacions SIG-WEB<br><a href="http://mercuri.icc.cat/website/mob_nf/mob1/mob2/inici2.htm?CONSULTA=Institut%20Cartogr%25E0fic%20de%20Catalunya&XYADDRESS=429486:4580392"><span style='color:gray'>Institut Cartogràfic de Catalunya</span></a><br>Parc de Montjuïc, E-08038 Barcelona<br>Tel.
