[Mapserver-users] Change Map-Filter via URL - Problems with Point Layer?

[Robert Fritz]

Hello,

I have 2 Point-Shapes and I want to change the "Filter" of the Layers via
URL.
But it seems not to work. If i use Polygon-Layers, everything works fine.

I converted the point Layer to Polygon Layer and changed nothing in my
Scripts -
using the Point Layers the Filter is not changed, using the Polygon Layers I
get the correct results.

Is there a difference between Point and Polygon Layers, using itemquery &
changing the filter via URL?
Or do I something other wrong?

Thank you,
robert


-------------------Map File:
LAYER
  NAME BaumPolygon
  TYPE Polygon
  STATUS On
  DATA Baum_Polygon
  Filter ("[Baumid]" =~ /^%baumid%/) # I change the Filter via URL e.g. to
("[Baumid]" =~ /^%baumid%/ AND "[ART]" =~/%art%/)
  CLASS
......

LAYER
  NAME Baum
  TYPE POINT
  STATUS On
  DATA Baum
  Filter ("[Baumid]" =~ /^%baumid%/) # I want to change, but it does not
change e.g. to ("[Baumid]" =~ /^%baumid%/ AND 						       # "[ART]"
=~/%art%/)
  CLASS
    Symbol "circle"
.......
