Hi Alexandre,
I fixed the issue as follows; creating a new layer with main parameters copied
from original. It’s quite similar of your code, because you clone the layer.
Old code:
layerPreview = layer.clone();
mapPanelPreview.map.addLayer(layerPreview);
My code:
var newLayer = new OpenLayers.Layer.WMS(layerPreview.name,
this.wmsbrowser.currentUrl,{layers: layerPreview.params.LAYERS,
format:"image/png", transparent: "true",
exceptions:"application/vnd.ogc.se_xml"});
mapPanelPreview.map.addLayer(newLayer);
Thanks for your attetion,
Antoni Vidal

Antoni,
Please, include the list in CC.
At this point, I'm not sure what could be done to solve the issue.

Hi Alexander,
I’ve made your change but doesn’t work. After that I’ve changed code in
WMSBrowserTreePanel.js just before addLayer to map, wich launch the error.
Look at:
layerPreview.mergeNewParams(
{'LAYERS': [layerPreview.params.LAYERS]}
);
console.info(layerPreview);
layerPreview.minScale =
null;
layerPreview.maxScale = null;
layerPreview.resolutions
= [275,100,50,25,10,5,2,1,0.5,0.25];
layerPreview.numZoomLevels = 10;
layerPreview.maxResolution = 275;
console.info(layerPreview);
mapPanelPreview.map.addLayer(layerPreview);
The first cosole.info shows “Infinity” in minScale and null next
properties. The second, shows the new values but error persist.
I don’t understand at all...
Any other suggestion ?
Thanks a lot,
Antoni.

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

Tema: Re: [Users] Error in WMSBrowserTreePanel.js
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.
