Dylan,
Have you looked at the following page in the documentation: http://docs.geoserver.org/stable/en/user/services/wms/basics.html#differences-between-wms-versions Jerome Wendell From: Dylan Parry [mailto:[email protected]] Sent: Friday, October 18, 2013 10:12 AM To: [email protected]; [email protected] Subject: Re: [OpenLayers-Users] Cannot read property 'yx' of undefined Hi, That’s similar to what I tried before, ie. yx: { ‘EPSG:27700’: false } Strangely, the error goes away when I set the above to ‘true’ but then of course the coordinates are all wrong so the tiles won’t load. I can’t understand why setting it to false would bring up an error when false is still a valid value? -- Dylan Parry Blue Fox Technology Ltd Tel: 01492 532100 Web: http://www.bluefoxtech.co.uk Registered in England and Wales, Company No. 0508226.

Wendell <mailto:[email protected]> Sent: Friday, 18 October 2013 13:25 To: Dylan Parry <mailto:[email protected]> , [email protected] Dylan, I have added the following to the same section of code that you referred to for some of my layers: yx : {'EPSG:4326' : true} See if adapting it to your projection makes any difference. Jerome Wendell From: [email protected] [mailto:[email protected]] On Behalf Of Dylan Parry Sent: Friday, October 18, 2013 8:06 AM To: [email protected] Subject: [OpenLayers-Users] Cannot read property 'yx' of undefined Hi, I’m trying to use a WMS with the EPSG:27700 projection. The WMS uses version 1.3.0, which is causing a few problems. I have got to a point where I cannot figure out what’s wrong. I am currently getting the following error: Cannot read property ‘yx’ of undefined and having read up a little, it appears that it’s due to the WMS version wanting to know whether to reverse the coordinates or not for the bbox parameter, but as the projection is unknown to OpenLayers there’s no yx property to query. My problem is that I have no idea where to add that property to. Here’s the code I have so far: <script src="~/Scripts/proj4js.js"></script> <script> Proj4js.defs["EPSG:27700"] = "+proj=tmerc +lat_0=49 +lon_0=-2 +k=0.9996012717 +x_0=400000 +y_0=-100000 +ellps=airy +datum=OSGB36 +units=m +no_defs"; </script> <script src="/Scripts/openlayers/openlayers.js"></script> <script> var map, opus; function init() { OpenLayers.ImgPath = "/Scripts/openlayers/img/"; var options = { maxExtent: new OpenLayers.Bounds(0, 0, 700000, 1300000), restrictedExtent: new OpenLayers.Bounds(0, 0, 700000, 1300000), projection: new OpenLayers.Projection('EPSG:27700'), units: 'm', scales: [10000, 25000, 50000, 75000, 100000, 150000, 175000, 200000], controls: [ new OpenLayers.Control.Navigation({ 'zoomWheelEnabled': false }), new OpenLayers.Control.MousePosition(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.LayerSwitcher() ] }; map = new OpenLayers.Map('map', options); opus = new OpenLayers.Layer.WMS( 'OpenStreetMap via Opus', 'http://server/wms', { layers: 'OpenStreetMap', version: '1.3.0', crs: 'EPSG:27700', format: 'image/png', }, { isBaseLayer: true, transitionEffect: 'resize' } ); map.addLayer(opus); map.zoomToMaxExtent(); map.zoomToScale(10000, true); map.setCenter(new OpenLayers.LonLat(195775, 223755)); } </script> I also have an onload event that calls the init() function to draw the map on the page. Any idea how to fix the error I’m getting? I’ve tried adding an xy property to the WMS bit of the code where ‘isBaseLayer’ is defined, but that didn’t seem to work.
