[mapserver-users] WMS Layer provided by MapSever rendering incorrectly in ol3.

[Neelesh Nirmal]

I have created a map using OpenLayers3 which contains two layers. First
layer is Open Street Map Layer and the second one is WMS layer provided by
the Map Server.
*Problem-*When i'm rendering first layer it is rendering properly no issue.
but when i'm rendering the second layer(provide by map server) it renders
incorrectly means it does not fit to its container and it is out of sync
with the first layer in terms of location. See this snapshot
<http://i.stack.imgur.com/Ac8xR.png> of the maps for more clarification. In
the snapshot top layer is wms layer provided by map server.

Also when i'm zooming or moving the map then both layers work correctly but
after a delay of few seconds the second layer(wms layer from map server)
again switches back to its initial position(Position that is shown in above
attached snapshot).


This is the code that i'm using to consume wms service.


var layer = new ol.layer.Image({
    source: new ol.source.ImageWMS({
          url: 'http://localhost:19090/rasters/world/wms',
          params: {
               'LAYERS': 'world',
               'mode': 'map',
          },
          serverType: 'mapserver'
     })});


This <http://pastebin.com/AWWWyBLE> is my map file.

    END
  END
END


I tried *ol.view.fit* method to fit the layer to its container but the
value of *layer.getExtent()* for the layer is undefined.

Also layers are rendering perfectly in QGIS and when i'm using the same
layer from geoserver instead of mapserver again it is working fine.

link to my stackoverflow post.

Pleas help me to find out what is wrong. is there any problem with wms
request format or the map file?
