[OpenLayers-Users] Problem related to names/labels of wards appearing multiple times (using map file)

[Jatin Ambasana]

Hello Everyone,

I have started using OpenLayers since some time now....

I am using a ".map" file to generate a map.
Following is the code:

*            map = new OpenLayers.Map( $('center') );
            var wmsurl =  "**
http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/OpenExtMap/MyShapeFiles/MyMap.map
*<http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/OpenExtMap/MyShapeFiles/MyMap.map>
*";
            var wmsmdi = new OpenLayers.Layer.MapServer( "Wards", wmsurl,
{layer:'Wards'});
            map.addLayer(wmsmdi);
*

Now the map that is being displayed shows the ward numbers on each ward
(since ward number is used as the value for attribute field called name).
Well thats fine, thats not my problem.

The real problem is that when we zoom in and as the area of each ward
increases the ward numbers are repeated on each ward at some distances.
This did not happen when we used the same ".map" file to generate map using
C# mapscript API.

Is it the problem of Openlayers or I need to do any changes in the map file.

Following is the code for my map file:
*NAME "iWork"

IMAGECOLOR 250 250 210
