[mapserver-users] Trouble with WFS GetFeature: get same feature returned multiple times

[Yewondwossen Assefa]

Hi,

  I just tried this with my test data and url similar you yours [1] and 
was not able to reproduce it locally using 5.4 and 5.6. If your data/map 
are not sensitive, would it be possible to send it to me directly and I 
will give it a try again (It would be easier for me to see the problem)?

best regards
