https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Layer/WMS.js#L180:L181 Maybe for some reason yx on your layer is undefined? But it should be set by the prototype of the WMS layer here: https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Layer/WMS.js#L63 Best regards, Bart On Oct 18, 2013, at 4:44 PM, Dylan Parry <[email protected]> wrote: > Of course, here’s the stack trace: > > Uncaught TypeError: Cannot read property 'yx' of undefined openlayers.js:951 > OpenLayers.Layer.WMS.OpenLayers.Class.reverseAxisOrder openlayers.js:951 > OpenLayers.Layer.WMS.OpenLayers.Class.getURL openlayers.js:951 > OpenLayers.Tile.Image.OpenLayers.Class.renderTile openlayers.js:446 > OpenLayers.Tile.Image.OpenLayers.Class.draw openlayers.js:446 > OpenLayers.Layer.Grid.OpenLayers.Class.drawTileFromQueue openlayers.js:460 > (anonymous function) openlayers.js:62 > e.(anonymous function) > > OpenLayers.Projection.defaults[‘EPSG:27700’] gives me ‘undefined’. > > -- > Dylan Parry > > Blue Fox Technology Ltd > Tel: 01492 532100 > Web: http://www.bluefoxtech.co.uk > > Registered in England and Wales, Company No. 0508226. > Registered office: Windsor House, 26 Mostyn Avenue, Craig-Y-Don, > Llandudno, Conwy LL30 1YY > > From: Bart van den Eijnden > Sent: Friday, 18 October 2013 15:41 > To: Dylan Parry > > Can you paste the full stack trace?
