Hi,

Please add also the GetFeatureInfo request that your application is sending.

Aihe: [mapserver-users] Wrong getfeatureinfo result from cluster layer

Hi,
When I click on a point in my cluster layer, I get the getfeatureinfo result 
from another point. That is, after the first click, I get the same result from 
every point. If the point is a cluster that represent more than 1 entity, I get 
the correct amount of results, but all the entities contains the same info. The 
only time the result changes, is when I zoom in or out.
It looks like it’s only when I zoom in really close, I get a correct result, 
but it’s only the first entity I click that is correct. The next will give me 
the same result as the first. A regular layer without clustering, works fine.

I'm using Mapserver 7.0.7.

Any help would be appreciated.

My mapfile:
