Description (Last modified by euzuro)

From a thread to the users@ list by Nick W: 

I'm getting a strange effect if I use a Mercator projection WMS server with a
bounding box which can take negative values in 2.4rc3 or the SVN version,
which I didn't get in 2.2.

Looking at the URL constructed to get the tiles, it appears to be URL-encoding
the commas which messes up the bbox.

i.e. the URL I get for the tiles in 2.4-rc3 is something like:

http://www.free-map.org.uk/cgi-bin/render?BBOX=-80000%2C6595000%2C-75000%2C6600000
&WIDTH=500&HEIGHT=500

rather than in 2.2:

http://www.free-map.org.uk/cgi-bin/render?BBOX=-80000,6595000,-75000,6600000
&WIDTH=500&HEIGHT=500

As suggested by Bart, this is related to #491

A simple patch for this would look like: 

Index: Layer/WMS.js

         var imageSize = this.getImageSize(); 
         return this.getFullRequestString(
-                     {BBOX:bounds.toBBOX(),
+                     {BBOX:bounds.toBBOX().split(","),
                       WIDTH:imageSize.w,
                       HEIGHT:imageSize.h});
     },

But rather than just patch it, we should probably:

  • Make it an option on the layer
  • Figure out which other layers are affected by this, if any. The WFS layer comes to mind.

Since the WMS spec says comma delimited encoded components for layers, styles, and bbox, shouldn't we make this our default?

Tests pass in IE and FF. Please commit.

$10K question: if MS makes the browser and the OS, why do tests run 5x faster in FF?
