<div class="moz-cite-prefix">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>
